Just want to say that I frickin love this TV. I was on the fence coming from a projector and "downsizing" a bit, but like Davyo, I have no regrets. This set is awesome, and it's awesome all of the time. I have a light controlled room (to a degree), so I could watch the projector whenever I wanted. But the image from this set is so much brighter and more detailed, has so much more depth and color pop that I simply can't be disappointed with the "smaller" screen. As a matter of fact, once the set is on, I don't even realize it's a little smaller than my screen was...and I likely wouldn't notice at all if not for the fact that my screen is still hanging just above the TV.
Interesting note - I played MW3 the other day. I left the set in movie mode since I'm not using any of the processing options anyway, and there was a noticeable lag...like I'd move my controller and at least a second would pass before there was a response. I switched to Game Mode, and there was no more lag that I could see. Now, I thought game mode simply shut off all processing, but maybe there's more going on there?? I don't know...don't care either to be honest. I'll just throw it into game mode when I want to play and all is good.
So far, still no audio sync issues. I run everything via HDMI through my Integra DHC-9.9 then to the LC80.
