I heard DVD at a dealer who was excited about it. Nice system, room, etc. I found the rear channels to be annoying, reminding me of the car audio ploy of "rear fill" to sell you to two speakers for the rear deck. I later read and article, probably stereophile, describing multichannel as a sledgehammer approach to solve the problem of creating a live space. I couldn't agree more. HiFi loses some aspects that make audio interesting when 5.1 is used, and a good room creates better space than more speakers do. At concerts, how often have you seen speakers at the back of the venue?
