If they use a 384 kbps rate, the sound will be fuller. Ideally, THX would use a PCM track instead, which has a bitrate of over 1500 kbps, but I doubt they'll do this. I don't see them using a 4.1 track to approximate the 70mm experience.

what was the bitrate for the 04 DVDs?
Furthermore, would the 2.0 decoded into pro-logic sound nearly as good as the 6-track (70mm) audio?
