I have both of those, but prefer Rock in Rio simply for the production. It sounds much fuller than DotR on my system. In fact, there's something screwy about the 5.1 surround disc in the DotR package. It sounds tinny and shallow. I was going to return that DVD but instead let a friend borrow it to see how it played on his surround system. Verdict, he had the same issue with the surround disc. But, since he didn't pay for it, he had a clearer head (not clouded with disappointment) and tried concert disc #2 (stereo mix) and lo and behold, it sounded a lot better! And it's also in surround, not simply stereo. I am only speculating, but I'm guessing they EQed the first disc somehow and left the mix alone on the stereo disc. I can't say for sure though, as I couldn't find any audio set-up options on either disc (it just plays the discs default audio track) to test it.
