Hello! I am GregK, and just found this forum and thought this project sounded amazing:

Disclord (Ty) is indeed a hard person to get ahold of. I've had some delightful conversations with him on quad audio, older video formats, including VHD 3-D videodiscs, and have had a lot of conversations of botched video releases where the audio has been altered.

Before I forget and speaking of Disclord, I want to mention the Sensurround DVDs, as this sort of thing belong in this thread, being that the original JP mix is a bass lovers delight.

When Universal released the handful of Sensurround titles from the 1970's, Universal released them in Dolby 1.1 (mono with LFE track). The results were less than stellar. I heard Battlestar Galactica in Sensurround during its original theatrical run , and the DVD's LFE track by comparison is certainly lacking. It was Ty who realized Universal had not applied the needed DBX NR to the original Sensurround tracks, so he manually decoded them himself with reportedly stellar results. I don't have access to a DBX type II decoder, but when I imported the AC3 track into my editor and did a significant raise on the LFE, it then sounded a lot better. This also applies to Sensurround encoded DVDs of Midway and Rollarcoster. And what is supposed to be the original 3.1 Sensurround secondary audio track on the Earthquake DVD is a joke. Whatever that secondary 3.1 track is on the Earthquake disc, it isn't true 3 track stereo, nor is it the original sensurround track. Stick with the 5.1 remix for Earthquake and call it a day.

Battlestar Galactica also offered optional directional steering for the low bass, which I can personally attest to working wonderfully. http://en.wikipedia.org/wiki/Sensurround Sadly, I don't see anyone finding a Sensurround Mod-III type decoder and decoding this track for directional steering anytime soon.

But back to Jurassic Park: A friend locally had owned the DTS laserdisc which sounded amazing. The 1st DTS DVD release of JP had a track that sounded almost identical to the Dolby Digital DVD version, and those listeners who compared it to the DTS laserdisc were (rightfully) having a hissy fit. Universal didn't know what to do, so they inquired with DTS and "requested the mix used for the laserdisc", and DTS supposedly complied. As soon as the limited edition DTS DVD (silent) repress was available, I did my exchange. I don't know if the DTS DVD repress is 100% accurate to the DTS LD (or the DTS theatrical mix), but the bass on that mix is substantially better than both the previous DTS DVD release and the Dolby Digital DVD release. I would love to be able to compare it to this new remuxing effort, if the file is still available somewhere. If anyone has leads or suggestions, please feel free to PM me!

I do remember there were a few DTS variations of the classic first spinning logos intro. I have a DTS trailer disc issued by WSR which has that, as well as a few of the DTS demo discs. I would have to check to see if I have both variations of that first intro. Oddly, my DTS DVD repress of JP uses the Piano DTS trailer instead.
