This is going to be fun. I've always regretted the time when theaters took out all their big systems and setups at the end of the Dolby-DTS war and all mixers toned their surround assaults down. You can't even find DTS theatrically any longer, if you're lucky enough to be watching 35mm chances are there's no DTS equipment.

For the 97 mixes (can't believe this is actually possible now) I'd say the easiest thing would be to match the DTS to a straight Laserdisc cap. Then you could add it to one of the broadcast versions, or even incorporate into other fan efforts. (I'm thinking this would give hairy_hen much to play with on his 70mm mix. He used the LFE on the lossy LD 5.1)
