The vast majority of HD-DVD and Blu-Ray discs don't have 7.1 sound. You could probably count the number that do on two hands. So, for now, I wouldn't bother with 7.1, unless you've got some very specific source material in mind - which, for the moment, are first-party PS3 games.Originally posted by: YOyoYOhowsDAjello

Not a big difference with most movies.
From what I understand, effective use of surrounds is becoming much more common on the HD movie discs but most of the time on regular material the surrounds don't even do that much.
That said, DD+/TrueHD/DTS-HD HR/DTS-HD MA are worthwhile in a receiver because of the higher bitrates that these formats support. You should be able to hear something of a difference with decent speakers.
