My HD Plasma has two component inputs. One of them is high-def and the other is not. I suppose the standard-def input is for use with a non-progressive scan DVD player or a standard-def Dish receiver. The high-def input works fine for either the Dish 811 or my progressive scan DVD player, but neither work on the standats-def input. I use DVI for the 811 receiver, but can not really tell the difference if I switch to component cables on it. Perhaps you either have two or more sets of component inputs on your set or there is a setup menu to change from standard to high-def on it. You seem to be the only one with the problem, so I would blame the set. Have you called Sony about it?
