"The original 1993 soundtracks were left off the UHD Blu-rays unfortunately. Schindler's List was an all DTS film, exhibited theatrically with a digital 6-track (5.1) mix for very early adopters of the DTS system, as well as DTS' MP Matrix system equivalent: DTS-Stereo. The later being compatible with already installed Dolby and Ultra Stereo cinema processors and was also a way to avoid paying Dolby fees for 35mm analog soundtracks. Many films throughout the 1990s were released this way. Unfortunately, the DTS-Stereo 4.0 surround mix which was heard by the vast majority of audiences at the time of the film's release was only made available on LaserDisc. We were unable to obtain this soundtrack. We investigated a DVD which reported a DD 2.0 option, hoping it was the same track as Dolby Surround 2.0 but it was a distributor printing error. Luckily, the original digital 6-Track DTS mix was put on all earlier DVD and Blu-ray versions of the film. We sourced a lossless version of this from the USA Blu-ray as an alternate option. The only difference being that the Blu-ray lossless 5.1 had its surround channels stored 3dB too loud; Left at theatrical levels as cinemas have their surround array calibrated 3dB lower (-82dB/c) due to old standing back compatibility standard for multi-track magnetic prints. For home video this is virtually always corrected, since home theater uses a linear calibration for all channels without a -3dB shift for the surrounds. The DVD had the surround channel stored at the correct level with the -3dB linear match. So we corrected that. Additionally we noticed that the audio on the new UHD release shifted periodically by up to 1 or 2 full NTSC video frames which is quite a bit despite the old Blu-ray being "frame perfect". So we found all of these points which took a lot of time, and shifted the audio back to line up with the new UHD BD version as needed. The synced and corrected track was encoded back to DTS-HD MA 5.1 on the latest encoder (more efficient) from Xperi with a full-rate core. It was also truly 16-bit, and we left it as such. Not 24-bit.
Yes, I've seen this. This is from the WILDCAT remux. You are right, but maybe the DTS disc could have a unique mastering.
