There’s some notes here on how to extract the audio from the CinemaDTS CD-ROM discs and sync them up to your target video file.

One thing though, the audio files on these discs are compressed and stored in APT-X100 files–one file per reel–with a bit depth/sampling rate/bit rate of 16bit/44.1khz/882kbps with a 4:1 compression rate. So, it’s not exactly a lossless representation of a film’s original sound-mix.
Happy researching.
