5.1 audio tracks are really recorded in 6 discrete channels right? How to non surround (stereo) systems playback 5.1 sound? Does the DVD player downmix to stereo or is there a seperate stereo track on DVDs? Someone keeps telling me 5.1 surround sound is encoded in a stereo signal. When I told him I returned my minisystem for a receiver because I want a digital input to have surround sound, he said I didn't need that since the 5.1 signal is encoded in the stereo signal. I'm sure 5.1 cant be encoded in a stereo signal, I think he's confusing Pro Logic and 5.1 He also says 5.1 audio is only 2 channels at the source and the decoder decodes the extra encoded channels out of the stereo signal, he says the source isn't really 6 channels.
