The audio mixes on the GOUT DVDs are the same as what's on the '93DefCol/'95Faces LDs, except that the LD sound is superior because it's uncompressed PCM. The GOUT DVDs soundtracks are compressed Dolby Digital. The mix that is used was done especially for the DefCol release- it combined elements of a few previous theatrical soundtracks.
Is that what you meant?
I think there are some preservations in the works here using the GOUT video with the LD PCM audio.
