from wiki: "most DVD-Audio discs also contain DVD-Video compatible data to play the standard DVD-Video Dolby Digital 5.1-channel audio track on the disc".\n\nDon't judge me for this but my Adele bluray has dolby digital audio. Weird. Sounds great though ... actually my favorite recording of hers.\n\nSpeaking of mcm, but on dvd, Sheryl Crow's Rockin' The Globe Live is pretty good imo. Track 4 on DTS in particular.\n\nYeah I think I have a dvd or two where there is a picture and a 5.1 DD soundtrack. I've been able to rip some of the dvd multich content with DVD Audio Extractor, too and put those on my hard drive plus usb drives so I don't need to pull out the disc. I have one DTS multich disc, the Allman Brothers at Fillmore East.
