He changed the mix WAY before the 2000 dvd

Is there any more info on what he changed? If this is the case then the only ways to hear the actual CDS mix would be to find a print that has it and decode it to listen to at home or go back to 1991 and find a theater that had CDS set up. Sadly no theaters showed it in CDS in my area at the time and I wouldn't even remember how it would've sounded then.

Even if one were to obtain the CDS mix how would you go about hearing it nowadays? I believe the first home release of T2 was in December '91. Had Rydstrom already remixed the soundtrack for the VHS/laserdiscs then or did that not come until later releases?
