Wrathchild, the sound on the RiR DVD is much better than the clipf of Hallowed taken from the NOTB DVD. I know what you are talking about, it sounds pretty awful.
All i can say is that while i can pick up some of the audio problems with the RiR DVD, its damn good and im glad i bought it. At this point due to my VCR not working, i am playing the DVD through mono speakers, and it sounds good through one speaker, so no doubt it will sound great in stereo!
The interviews with the guys during their spare time is worth the money alone.
MAIDEN RULE!!!
