If you've got the means, 5.1 Blu Ray audio. It sounds absolutely fantastic. I mean, it looks great, too. It definitely is the best looking DVD and best shot DVD, and is also the best sounding. Performances I guess are more subjective, but on a musical level Rock in Rio always has sounded like I have another TV on in the room tuned into white noise. I dunno if that's the mix, the band being sloppy, or what. I can hardly hear Bruce sometimes, too.
