I've had an AppleTV for a while now, and its recently begun to annoy me because its off center on my screen. Its connected via HDMI to my Yamaha RX-V663 7.1 receiver, which is connect to my TV via HDMI to DVI Apple cord. Everything works great, but its slightly off center, its like the AppleTV picture is larger then my tv (ie it looks like I'm missing things on the left side of the screen). This is really obvious when browsing purchasable or rent-able movies. Any suggestions?
