I have heard alot about people saying to stick with the PCM audio when making the DVDs. However, I think it would be best simply to grab the 5.1 audio off the upcoming official DVD release and then take out any sound that was different from the original and mix it with a 5.1 track off the LD. I figure that 95% of the sound on the DVD will not be diffferent from the original release and it will sound better than the LD audio (plus the theatrical release was in surround sound I believe so it will be staying true to the original).
