Jurassic Park DTS laserdisc is a beast. The 1997 ntsc versions of the Star Wars Trilogy Special Editions are the only home versions of those cuts with a 5.1 Ac3 track. Love my Cld-d925.

Another plus point for DTS laserdisc was used the original full 1.5mbps data that was on the Separate theatrical release CD-Rom. When DVD eventually came out they followed the Laserdisc market, having the consumers pick which audio format to play. However as DVD burst into the mainstream, the cheaper Dolby Digital titles with bonus features left the more expensive "bare bones" dts movies for dust. DTS decided to slash the audio stream in half down to 768kbs, Still higher than Dolby, but half what laser had. Jurassic park on DTS laser is amazing for that!
Jurassic Park is the GOAT when it comes to surround sound.
yup! Dont care how old I get, I will play that scene as loud as I can every chance I get :)
did you see the vid?
laserdisc has hands down the best audio for these old movies, they're so so much better than those bluray remastered audio nowadays
Great video :)
You have a really good setup. I have yet to get myself a Laserdisc player decoded with Dolby Digital and DTS to find evidence that the sound is better on Laserdisc than it is on DVD. In truth, I never saw a film on laserdisc. I have watch DVD for years and DVD sounds great in 5.1 surround sound, and I've been watching Blu-ray discs since by the end of the 2010s on a Sony Blu-ray/DVD Home Theatre player (BDV-N790W) and they sound great too.
When I get a Laserdisc player with an Onkyo AV Receiver with 5 Klipsch speakers and a subwoofer and a RF Demodulator, I would have to see it for myself.
It’s in the mix.”
As far as the audio goes, typically the Laserdisc version of audio is taken from the cinema master.
Laserdiscs began with FM analog audio in 2 separate channels (not matrixed stereo). The first implementation of digital audio on Laserdisc, in 1984, added 2 discrete channels of lossless CD quality PCM audio, (exact same spec), typically including a dolby surround encode, sounds great with today’s Dolby PL II decoder which takes it to 5.1 channels. AC-3, (AKA: DD or Doby Digital), was a digital lossy encode that came after, but, gives 5.1, (sometimes 6.1), separate channels, where previous dolby surround was matrixed, and the rear channel(s) in older mixes had a limited frequency range. DTS was also implemented on some Laserdiscs, via a S/PDIF optical or coaxial connection.
Even with higher quality lossless Dolby True HD or DTS HD MA 5.1 or 7.1 (or immersive) available on blu-ray discs, almost always the mix has been redone for the home version, (something I think began during the DVD era), so it does sound different, sometimes inferior to what was put on laserdisc. It is rare to get a cinema mix on a blu-ray, but, a few discs have claimed to do this.
🤘👍
The empty spots to the right and left of the setup are were the subs go...they were being cleaned when I filmed this
Excellent video. Nice to see others flying the ac3 dts LD flag! Two points I would mention: Speed did get an ac3 reissue that has an identical jacket and catalog number. It took me ages to find but if you check enough copies you’ll find one. Also all early releases of the film in digital are 5.0 for some reason. I’m super envious of your dts copy!!!
Also on T2 there is an ac3 release and it’s very important. The final US release and initial us dvd release share the same master but for the film’s first ever 5.1 on video the label went to the original CDS theatrical audio 5.1 master and simply used that. Thus this release is the only one to use the revolutionary early 5.1 mix that absolutely obliterates all of the later home remixed tracks. (And this is coming from someone who likes the LD 2.0 surround mix!) This is the same case with the Jurassic Park home mixes versus the original theatrical dts.
Of course the CDS mix was only used in the big cities for the initial premiere engagements and so the final LD/first dvd is only the theatrical cut. I’ve never found the ld as it’s quite pricey and rare but the dvd is identical and can be found in used bins for 99 cents where I finally found mine.
Oh you enjoy Jurassic Park in DTS? Enjoy the end! th-cam.com/video/6RhF7jCALAQ/w-d-xo.html
I miss these reviews/overviews man!!
well get ready - one a week is coming on various subjects. My TV is WELL overdue for a review...and other stuff ;)
Ill be making a video on this later but it goes as follows. Lets just say for simplicity you have a LD player only. You go from the back of the LD player to the demodulator with an RCA cable into the AC3 port. You then go from the demodulator to the reciever with an optical or digital coax depending on what you have - BOOM Dolby digital. For DTS capable players you would go right to the receiver with optical...but you still need the demodulator for the AC3 audio.
Help! I just received a DTS LaserDisc in the mail today but it won't play on my AVR. I have a Pioneer DVL-919 LaserDisc Player and a Sony STR-DE697 AVR which has Dolby Digital EX and DTS-ES decoding. I have a demodulator for my AC-3 discs and it works flawlessly. I tried both Optical and Coax cables straight to the AVR for DTS but my AVR shows a decoding error message. I also tried switching audio tracks on my LaserDisc player but it didn't help. Am I missing something?
Nice video....I am currently looking to by a demodulator without spending 150 bucks. I can not wait to hear these laserdiscs in DD I have quite a few that I have collected over the years.
T2 laserdisc With Dolby Digital is available and it is a USA release I have a copy but it is hard to find and back in the day when laserdisc was out AV receivers had AC3 Demodulators built in so you didn’t need extra components
Actually, there was an AC-3 version of Terminator 2: Judgement Day released in America, but it wasn't Full CAV although the last side was, and it was the theatrical cut.
So..i'm wondering: my receiver is a Pioneer VSX-933, do i need to use a seperate sound processor to get Dolby Digital sound? (probably have to, but i'm not sure)
i just bough a dvl-919 i think it`s a japanese version as the player is a silver version as to where the normal versions were all black. on the back of the player has a switch says tv pal/ntsc and auto i don't know what all those options are for dont know if it`s rare to have that version as all the black model dvl-919 don't have that feature on any of them.
Nice video! Wish I could give you my 1000 of laserdisc as they been heading to the bin slowly.
You didn't seem to notice that "Aspect Ratio" setting on your receiver- set THAT to 4x3 and it will output an upscaled signal in the right dimensions. I have a Marantz receiver with that same interface and run all my analog formats through it, no need to adjust the TV between those and 4K/HD sources.
I can't because I'm using a 4 x 3 projection screen and if you watch the video when I switch between the television and the projector the aspect ratio is perfect at least it's running that way and has done so since I installed it :-) maybe not in the video. I have everything set to AI so there's no upscaling but when I switch over to a Blu-ray or whatever it's the proper resolution. If I switch it to upscale/anything above 480 I the aspect ratio is overridden almost like it thinks it knows what it's doing and will not allow me to zoom or stretch properly to give me the proper aspect.
Before in the 1930's after the Viotaphone 78RPM discs then it was optical soundtracks of mono with the odd few stereo ones then back to more mono then magnetic stripe came about in the 1950's mag tracks offered 35mm four track mag the rarest, and maybe the best still the best six-track mag 70mm it was at first noisy then Dolby came in during the late 1960's and not too soon had an actual working NR noise reduction that really worked and first movie was Callan early 1970's mono with Dolby A-type not too far away optical SVA twin track Dolby Stereo A-type came about some of the early ones had no surround.
First surround on Dolby Stereo was A Star Is Born, got that on LASERDISC!
The biggest break for Dolby labs was STAR WARS and CLOSE ENCOUNTERS OF THE THIRD KIND 35mm Dolby Stereo A-type and both also released with sub bass track on 70mm the first biggest break for sub bass was EARTHQUAKE in SENSURROUND few years earlier with a sound generator that is basically a clever box of pink noise that used pilot tones of 12Khz on the film print to trigger the SENSURROUND MOD I and later versions of MOD II and MOD III SENSURROUND retired before end of the late 1979? But there they are classics EARTHQUAKE is the best!
STAR WARS / CLOSE ENCOUNTERS offered LCR mono surround and SW track.
Year later SUPERMAN THE MOVIE offered first EVER! Split Surrounds, stereo surrounds that today is commonly called 5.1 After Tom Holman called it 5.1 at sound convention during the late 1980's.
The 70mm original of format 43 is different layout over 5.1 for the cinema processor. 70mm six track on some of the tracks was bit frequency limited in the low range and just tiny bit in the high, high range of around 18Khz then again human hearing is not all good at high, high frequencies that need to be greatly amplified to be even be heard slightly heard?
Dolby SR-D offered greater frequency range down to 5Hz to 20Khz if you can hear 20Khz? Feel 5Hz with bass shakers is possible with subs you'd need so many to double up with loss and EQ shape it all to be even noticed a little bit below 20Hz. All the rest of the bass in the other channels should be FELT if drowned out by the sub then the sub and its levels are far too high.
Today only few cinemas that run 35/70mm in selected cinemas still showing 5 perf 70mm and not that crappy imax 70mm or that crappy fake imax called LIEMAX Yuck.
Regular 70mm RULES and imax 70 SUCKS.
Look at SPEED THX LASERDISC here looks better than that fucking bluray that fucking 4k. I have turned my back on fucking bluray and fucking 4k fucking uhd. Utter Horrid Diarrhoea UHD. I even thew uhd in the cat litter box and my cats took a shit on bluray 4k uhd.
So let me get this straight for DTS I need a separate decoder or connect an optical cable straight from the player to the A/V receiver for that sound, but if I use a Dolby Digital decoder I get nothing out of it, and without the decoder I get static? Also a second question I'm looking for a couple of LaserDiscs from late 1999 to early 2000, and they both have Dolby Digital Surround EX which is the same as AC-3 5.1 but with an additional channel added to the rear of the room, do you know anything about EX and how to decode that properly. Thanks
From what I remember about DTS, they said that if you took the optical output from a laserdisc player, you can put it in a receiver that does DTS and it will play as DTS. No demodulator needed.
Dolby Digital didn't sacrifice the analog tracks and they decided to put the AC-3 track on the one analog channel since most people couldn't afford AC-3 at the time but more people would use the digital output for stereo out.
Just an fyi Coaxial is superior to optical due to the fact that optical out requires a conversion to optical then back from optical leaving room for errors in the conversion processes
The worst thing for me is that now that I finally got a laserdisc player (two actually, a CLD-D504 and CLD-D505.... the 504 came with a bundled in AC3 demodulator and a TON of movies, so I had to get the second player ;) )...... the 504 and 505 BOTH have the AC-3 output but neither one has the optical output so I can play DTS discs. :/ And back in the 90s, I had a CLD-3070 which had the optical output but no AC-3. :/ I never owned any DTS discs because DTS didn't really become affordable until DVD and many receivers didn't have both Dolby Digital and DTS. :/
Shame though. I used to really like the sound of DTS on DVD too..... but there weren't many DTS discs around where I lived and AC-3 was on almost all new releases near the end.
Oh well.... what can you do?
Can you play AC3 LaserDisc on a regular LaserDisc and still good audio like two channels not 5.1 I have a pioneer LaserDisc player was wondering if I can still play the movie on regular LaserDisc player even though it's AC3 please let me know have not set up my system yet thank you very much
So the answer is simply is yes what they did was they included a mono audio track in one of the channels of audio in case you do not have a decoder kind of like a last resort kind of thing most laser disks however were simple to channel stereo so most people never knew about it back in the day it took a lot of equipment and money to get up and running- AC3 To me sounds better than anything out there right now including Blu-ray audio
I know how you feel, in fact I still have my 80’s original SSI Dolby surround 3 channel box $350 and the original millennium DTS decoder $800 they were both pricey..
Indeed. More videos to come! What I plan on doing is a review of every major lazer disk that I have both picture quality the sleeve or Box it comes in extra in of course more videos on actual DTS and Dolby Digital content I'm probably one of the few people in the country that currently has a fully functioning system
I know it is 4 years later, but set your projector's aspect ratio to 4:3. It will solve your problem. Laserdisc is 4:3, and when movies are widescreen, they are 4:3 with black underneath and above the picture.
If your receiver has DTS Neo:6 decoding, why use Dolby Pro Logic II instead of that if I may ask?
After years of working with this equipment I can tell which one is which by the way it separates the audio in the speakers it sounds crazy but I prefer Dolby Digital for sound separation however the DTS neo I prefer for TV shows but I try to watch in. I’ll be digital/DTS 5.1/5.2 whenever possible
What is that decoder thing?
1:15 : Fuck it! We'll do it live. lol thats what it reminds me of
I'm guessing you've connected decoded processor outputs to corresponding inputs on your receiver. I have a Denon AVR-5200W that doesn't have inputs for processed surround channels and I know that some receivers and control amps do. Does your Denon have those inputs?
Actually I have it hooked up to Waze laser disk player goes from theACthree output into the demodulator then it goes from the modulator to my receiver with digital coax. The laser disk player also has an optical cable running from it to the receiver directly for a DTS pass-through given that the receiver can handle the decoding :-)
@@bsgtrekfan88 I should consider buying a decoder like yours. In the days before DTS I used to connect my Pioneer SP-D07 processor preouts straight to the power amps.
How you connect the Dolby Decoder - SDP-E800 with Receiver?
Hey simply connect it with the optical connection for my receiver it at the codes for the AC three connection
@@bsgtrekfan88 in Digital 3 out?
You didn't need three components in the 90's tho, they made home theater amps with built-in AC-3 decoders.
Yes you are correct but not everybody could afford them and most people had these components for something similar
@@bsgtrekfan88 I thought they were at least more affordable than the DTS ones, that's why AC-3 was more common of the two.
All early AC-3 processors and AC-3 AV Receivers decoded only Dolby Digital and Dolby Pro-Logic. DTS came later and only but a few high end AV Receivers incorporated an AC3-RF Input with both Dolby Digital and DTS decoding options. Furthermore, as LD winded down in popularity, we started to see AV Receivers sporting both Dolby Digital and DTS decoding as a ubiquitous surround option but AC3-RF inputs were now being removed.
Fast forward to today, the only way to have all the decoding options available is to run a set-up just like in this video. Get a current AV Receiver and mate it to an old AC3-RF Processor and run AC3-RF out and Digital out of the LD player to the processor. Then connect a Digital out from the processor to the AV Receiver so it can transfer the unprocessed digital bits of Dolby Digital and DTS to the AV Receiver (so essentially speaking, the processor is just used as a digital switch box and nothing more).
Exactly
Yup!.. was looking to buy an yamaha or sony rf demodulator and then I came across a pioneer vsx 09tx with built in ac3.. it's a flagship model that's what I read online...paid 100 bucks free shipping on ebay brand new in box a few days ago. Receiver worth 1800 without tax in 98.
Do blu rays also support pure uncompressed DTS, or only Laserdiscs?
DTS is still compressed for LaserDisc. However it uses the full bitrate which is 1.5mbps whereas for DVD it uses a reduced bitrate.
Dolby Digital & DTS are both lossy codecs that use lossy compression.
@@Riddler95 Last time I checked, some DTS DVDs are also in full bitrate (1.5mbps). The later DVDs with DTS Digital Surround Sound is 754kbps.
Correct. I forgot to mention that in my comment. The early DVDs that used offered DTS used the full bitrate, but it was taking up too much disc space and they were sacrificing video quality for the audio. So they brought out the reduced bitrate which still sounds great.
It is neat to see someone make an in-depth video about 5.1 audio in Dolby Digital and DTS on LaserDisc. I am still in the hunt for an AC-3 Demodulator but hopefully I'll acquire one soon.
Terminator 2 was actually re-released on LaserDisc in 1998 with a 5.1 audio mix in Dolby Digital. However, it was the Theatrical Cut.

they are all over Ebay ;) And T2?! Well now I am on the hunt for it...... ;)
I am trying to score an AC-3 Demodulator locally. They go for a pretty penny on eBay and I live in Western Canada so buying one from an American seller would cost alot more in the end. It looks like the Yamaha APD-1 is the most AC-3 Demodulator and it will probably be the one I get.
Have fun hunting down the AC-3 edition of Terminator 2!! It will probably sound great.
hey I might be getting a different AC3 demodulator...want to grab mine? Shipping and $50 and its yours ;)
Riddler95 I am selling my demodulator for one of that better fits my entertainment center if you would like mine let me know I’ll give it to you for 50 bucks plus shipping which according to eBay is the cheapest of demodulator that you can get :-)
Which model is your current AC-3 Demodulator and are you in Canada?
Laserdisc did it first! Great video, but heads up! my DVL-919 just died, looks like the lasers for the laserdisc side are dead, horrible pixellated washed out picture, I found a CLD-2090 somewhere so that is my backup player, sad, these great laserdisc players are all dying! and good luck finding someone that still works on them
I kept getting the feeling during this video that you didnt want to make it. You seemed annoyed by the entire process.
Great idea for a video. Sorry to hear about the fire. How did it start? Faulty wiring? That's what happened to a friends house. Anyway, I hope no one was hurt. Please understand I'm not here to troll you. Just the impression I got.
TimothyTim PSP I don’t know why you thought that but I don’t film these with a script it’s usually off the cuff and after work so if anything I might have been tired
Awesome!...new subby in de house baby..
That's not how Dolby Surround/Pro Logic works. It's a matrix-based surround format that hides a surround signal inside a stereo signal. It is not the same thing as taking a stereo signal and attempting to fake surround out of it.
Technically it is it's faking surroundsound when the original stereo mix iz present instead of 5.1 it's a figure of speech/wording my friend. It's dumping down things and using terms that ordinary or non-audio people will understand
Never turn overscan on. It's useless for Laserdisc.
normally I would agree - but as you saw in the video - the player with its 4% scan puts the entire frame perfectly within the projector screen without loosing picture.
@@bsgtrekfan88 I understand.
I guess the difference is that I setup my LD and screen with overscan off, therefore my screen fits perfectly with it off.
That way, when I turn overscan on, it overscans; unlike yours which makes it "fit" when you turn overscan on (which I'd argue is incorrect, but whatever works for you.) 👍
Indeed. It is nice to see someone else appreciate laser disk besides me :-) more videos are coming on the subject
You want the ultimate Jurassic Park get the DTS it blows away all the rest I found it for 45$ same for GoldenEye DTS edition it's better than AC 3 Dolby digital laserdisc
Jason Koestner You might want to check out the video that came out one or two after this one :-)

21:31 You can't blame Fox just because they have to protect their properties via copyright.
No but what I can blame is TH-cam’s overly aggressive copyright system when one is literally doing everything by the book yet they still throw out a claim....bs That eight ignores every single aspect of fair use such as for review purposes or teaching moments/reviews/overviews
why do you swear a lot
Hell yes :)
