Just starting to get my feet wet on concert DVD's. The first one I watched this weekend was Steve Vai's Live at the Astoria London. Awesome show BTW-great PQ and audio, wish it was 16:9 though. Anyway, the show itself was almost 2.5 hours. For some reason they decided to put the layer change in the middle of a song. Is this common? They could have easily put it between songs IMO. I found it very disruptive, as it was not a graceful change.
