Just curious: Do you think a Stereo PCM track mixed with Pro-Logic II decoding in mind be preferable to a DD 5.1 or DTS track? I guess the question is whether PL II's 5.1 derivation scheme is good enough that something mixed specifically for it could be given the same sound placement as in a discrete mix. You would get an uncompressed 5.1 mix. It would be playable through any stereo or TV. It would take the about same amount of space as the DD 2.0 + DD 5.1 + DTS option set that is found on many DVDs today. I guess the big issue would be that the people with DD and/or DTS hardware would have to use Pro-Logic I, but I'm curious about what people think of this anyway.
