I thought that could be the case, but definitely determined it is an entirely different cue on it's own completely.
I didn't realize they confirmed there was another track missing already. Do you remember if they said why it was left off? Actual missing sources or damaged reels?
For my complete edits I just ended up extracting the audio from the DVD and using Audacity to remove the vocals. It doesn't sound too good, but it is good enough for me. Does anybody know of any really good software that can remove background hiss/vocals and fx better than Audacity? Or any tips when doing it? I just invert the audio and make the channels mono when I do it.
