Someone on this board had access to some SE DTS discs a couple years back, but I have no idea if they could figure out how to play them back. The players used in a theater are proprietary and synch up to a timecode embedded in the film.

For discs produced before 2005, it is possible for certain pirate/hacker types to rip the audio off the DTS theater discs. I have no idea how, or what equipment is involved.

After 2005 the discs were encrypted, and this encryption has AFAIK never been cracked.
