I received my limited edition copy of The Roundhouse Tapes DVD today. While the epic package mesmerizes, I was dismayed to find upon watching on a MacBook and listening with headphones that the volume levels of the audio recording itself fluctuate pretty badly throughout most of the show. While evident through computer speakers, the defect is not as clear without headphones. Is there something defective about my copy, or is this a true mixing/mastering error? It makes listening sort of like a seizure. Has anyone else noticed this with or without headphones? I'd appreciate anyone taking listens for this with headphones, especially if you haven't noticed anything before. Worst case (if my copy is defective), I'll buy a regular copy whose disc I'll replace this one with; I doubt there's any difference in discs between the editions so I'd feel as if my limited one was still 'complete'.
