Greetings! I'm currently looking into buying an AppleTv to use with my Panasonic 50" Plasma. My only apprehension would be the video quality from the ATV on a TV this size. Is anyone using ATV with large flat panels? I know this depends on the actual source of the video/movie to begin with, but for some examples: a standard downloaded movie from iTunes store, a downloaded HD movie when available from iTunes, and a ripped dvd from a software package (handbrake, AnyDVD). Thanks for any feedback!!
