I was on Best Buy's site today and looking at the specs for the Bose Lifestyle 48 system. (Why do I feel like one of those guys who says "I was just changing channels and I saw 4 hours worth of movies on Cinemax.") Anyway, the specs for this $4k system say that it doesn't have a built in Dolby Digital decoder, though it does have a "Bose-exclusive Videostage 5" decoder. Is this right? Does this $4k system have no way to play Dolby digital 5.1 in 5.1 sound?
