I'm in the market for a new tv and I currently have a Panasonic G10 plasma. I was considering going with another plasma but i'm also considering an LED LCD tv. My only concern is lip sync. The TV will be running like this: Direct TV box - Emotiva UMC-1 - TV. Or the same but a PS3 instead of a DTV box. Do all LED LCD tvs have lip sync problems? I'm not too smart about TVs so any help would be appreciated. Also, what is the best and most affordable TV around 50-55 inches?
