Ok I understand Dolby Digital and that it is true surround sound. This post is in regard to music concert dvds specifically. I understand that if I switch the setting on my receiver to 6 channel stereo that the music is being played equally through all speakers which of course defeats the purpose of Dolby Digital. However, there's no denying that playing music in 6 channel stereo surrounds the room in music much more since the rear speakers are just filler. My question is this. If I choose to play music concert dvds this way, what specifically am I "missing out on" or being denied if I don't play them in Dolby Digital? Like I said, I know that Dolby Digital spreads all the elements of the music to speakers separately and that each speaker has their own purpose.. and that playing the music equally through each speaker equally defeats this - but hey it still sounds great and fills the room more. Please don't reply with "do whatever sounds best" - I'm really curious to hear from those who can give me specifics that can tell me what not using the Dolby Digital setting for music concerts is depriving me of. Thanks!
