I just bought a Panasonic BD80 BluRay player that is hooked up to my Sony 40" LCD HD TV with an HDMI cable. For whatever reason NOTHING will play full screen as there are black bars at both top and bottom of the picture, like it was "letterboxed." I have tried all the various format settings that the menu offers as to screen format size and that does not solve the problem. I have another DVD player, not a BluRay hooked to the other HDMI input and that will play all the DVDs full screen that the other will not. I tried calling Panasonic and they could not seem to help, hopefully someone here can.
