Star Wars 1997 DTS CD-ROMs (Released)
Time

The DTS theatrical mix may very well be the same as the Dolby EX mix.  Since Dolby EX was merely 5.1 with the 6th channel matrix out of the surrounds, this could easily be on the DTS CD.  Later DTS CD's that had this were usually noted as DTS-ES.  I'd almost bet that the DTS mix is the same.

According to my records as well, it was DTS-ES.  I do believe this was also an SDDS-8 title as well.

Star Wars 1997 DTS CD-ROMs (Released)

For those that haven’t heard, I have discovered a way to rip cinema DTS CD-ROMs for use in preservations.  Along with ElDonate, we successfully preserved the original 6 track mix for Jurassic Park.  Check out this thread for details.

What I’m wondering now is if anyone out there has the SE DTS discs that we could use for preservation efforts.  I’d imagine they aren’t much different than the AC-3 tracks on the LaserDiscs, but the compression will be much less severe.

I’m able to rip the discs but the editing is something beyond my skill.

For that matter, are there any other titles out there that anyone has that they may want to preserve?  The ripping tool is pretty outdated and thus won’t work with any DTS CD’s after 04-05ish.  I have the Epsiode III discs, but they are not able to be ripped.  The rest of the films should be doable.

Preserving DTS LaserDisc tracks, specifically Jurassic Park

I'm hoping those that PM'd me have had success getting the track to work.  I'd love to hear some feedback.  Perhaps you can even note what sort of gear you're listening on.  

I'm listening on a Pioneer THX receiver, Klipsch speakers, and a JBL sub.  I made an AVCHD that runs off a USB hard drive connected to my Blu-ray player and have had it on virtual repeat this week.  I can't stop checking it out when I get bored with Netflix. :)

I suppose I'm making up for lost time eh?

Yep, APT-X100.  I don't even remember how I discovered it way back when, but I did.  I'm just glad that an old CD backup I did of my old PC had the files on it when I got curious again about Jurassic Park.  

Jurassic Park was indeed the first film to be released in DTS.  Little known fact: this film along with several others in the early days had a 6-track and a stereo DTS release.  The idea was that many cinemas were not fully equipped yet for 5.1, so they could install the DTS-6 processor, but in a stereo only configuration.  Therefore, the stereo DTS discs contained a 2 channel track in digital sound, albeit compressed, and the cinema processor could decode it like pro-logic.  From what I hear, the 2 channel tracks might not be able to be ripped, but they are compressed tracks anyhow.  

The aforementioned DTS trailer that was attached to Jurassic Park, and some other early DTS films, was also notoriously played in non-DTS houses because many cinemas just left it on the head of the film.  It'd be cool if we could edit the existing home video version to match the audio from the JP DTS discs.  Basically, after the disc flies out and the words "The Digital Experience" explode, the trailer ends.  It's pretty cool!

The surround attenuation was only for surround info only since the DTS-6 and DTS-6D processor were to be set at 82dB output instead of the standard 85dB.  Subs were set at 91db.  

I'd be up for ripping the 97SE, but I wouldn't be able to edit.  Does anyone out there have them?  I'll have to get around to posting in the other forum unlesssomeone chimes in here.

Not sure what the error was with tsmuxer: worked like a charm for me with my Blu-ray.

I'm also still catching up on PMs.  I just got back from a very very wonderful wedding...and the gin was free.  

My cousin spared no expense.

Thanks everyone for the feedback.  DTS cinema discs can be had from a few places, but yes, not always easy to find nowadays.  The content on them is digital, and are playable in a DTS cinema processor.  That processor with the discs syncs to specific films via a printed timecode on the print.  The beauty of the system was that the sound was off the film, and away from potentially being damaged.  Since the timecode is simple and also very close to the picture, it was well protected.  

The compression rate was something like 4:1 I believe, so our source for this project was technically lossy, but the final product was preserved in DTS-MA as to not lose any more quality.  As for the LFE, it was in the surround channels (also helped save on disc space) and filtered out at 80hz.  The DTS processor itself had this low pass filter built in, so it actually output 6 channels to a given cinema processor.  ElDonate applied a similar filter and extracted that bass information so that we could make it a true 5.1 track for home use.  The worry was that someone would have their surrounds not set to pass 80hz or below to a sub, and damage their speakers.  He also adjusted the levels of the surrounds and sub based on how a DTS cinema processor was calibrated since that also differs from a home system.  I'll let him explain that a bit more since I wasn't the one actually doing it.  We based that information out of a DTS manual that we found.

This plugin for winamp is ancient, and never got updated when DTS started encrypting their CD-ROMs after about 04-05, so only films prior to that with DTS tracks could be utilized.  I remember screwing around once with Kill Bill Vol. 2 when I first discovered it.  I just never thought of putting it to any practical use.  

In this case, this means the 97 special edition soundtracks could be ripped and preserved, if anyone can find the discs.  I'd be up for doing that if someone can find them.  I can only rip though, as I have no knowledge on how to edit it all together.  ElDonate is a saint for doing the work he did!

I haven't done an A/B yet with the LaserDisc, but honestly, this mix does sound a bit different to my ears in a very very good way.  It's perfect and just how I remember this movie sounding.  Why Universal could not have done this is just beyond me.

Alright folks, big update:

Together with ElDonate, we have found a way to preserve the original theatrical 5.1 mix.  We didn't get it from a LaserDisc either.  

I found a copy of the theatrical 6-track DTS CD's, and using a very old plugin for a very old version of winamp, I was able to extract the the 5 channel stems for the movie.  It is 5 channels because theatrical DTS had it's LFE data stored in the surrounds, and DTS processors sent anything below 80hz in the surrounds to the sub.  

What we have here then is exactly what you heard in a DTS cinema.  And it is glorious.

I'll let ElDonate chime in about the process he took to create these tracks, but in the meantime, PM me if you're interested in getting the track.  We encoded it into DTS-HD MA for syncing with the Blu-ray.  ElDonate, thank you very much for taking the time to do this! 

I can only host it for about a week, so if you want it, let me know soon.  Hopefully after that, someone else can host or up a torrent.

Mr. Hammond, I think we're back in business!

GoldenEye and Tomorrow Never Dies both have excellent DTS tracks on the LDs, and yes, a preservation of them would be worthwhile.  Ideally, I'd love to make preservations of both Bond titles, Jurassic Park, and Titanic.  Anyone yet know how to rip these easily into a workable format?  An analog method would be easy by outputting analog 6 channel from my processor, but I'd rather do this digitally as to not lose any inherent quality.

As a big fan of the movie, I was disappointed to not see the original 5.1 mix preserved, but instead we were given only a new 7.1 option.  While this mix is good, it's definitely very different.  Some sound effects have been put in different places (see the raptor paddock scene) and a weird echo added to dialogue in many spots.

Either way, I love the sound of the DTS LaserDisc, and would like to eventually sync it with the Blu-ray image, which was not perfect but better than any other release.  Of course, I don't have the sorts of equipment to do such a thing but I would love to at least try and preserve the LD track, but I'm not sure entirely what sort of sound card I'd need to do it.  Preferably, I'd like to keep it in the digital domain so there is no sort of quality loss.  It is my understanding that the track is encoded on a LD at 1200kbps, disguised as 44.1khz LPCM.  

Of course, if I could master this, I'd love to do it for several other titles with exceptionally good DTS LD tracks (Titanic, Apollo 13, GoldenEye).

Let the discussion begin!

What does the blu-ray set have to offer?
Time

I did hear that they aim to keep the bitrate very high for the video, so that is definitely an improvement over what is out there now I'd say.

I'm hoping they do fix some of the crap they pulled in 2004, specifically the coloring and the sound mix for ANH.

I'd also wager that some folks on this forum may be more adept at creating an excellent mix for the trilogy than anyone at Lucasfilm.
