I probably wasn't in the sweet spot, but it sounded to me like the sound was coming very clearly from the L and R speakers, not the middle of the TV. I don't have this problem when I use surround processing on CDs and only listen in 4.1. It's also been awhile since I've tried it.
Actually, it was the lack of a center channel that led me to these forums! I tried watching T2 Ultimate Edition in 2.1, and I could barely hear the dialog. My first post was about whether I should get an Axiom center or some other brand... and I still don't have one!
