Hmm, this has taught me another lesson about buying into music I wouldn't necessarily buy without checking samples first. (We've currently got the first album, but I hardly ever play it.) There's definitely stuff in the rear channels other than ambience and crowd noise. I really don't like what's happenning at or near the bottom end on the DTS 5.1. It's much bass lighter on DD 5.1 on my system - maybe I've got a setup issue. There's something really unpleasant for me about that sound on either 5.1 stream. Also the video seems out of sync with the video (maybe a frame out) which takes away from what could have been a more immersive experience. The performance retains (at least some) stage chat about the songs which makes it more interesting for me.
