I've had an HD-Ready set for over a year now and enjoy the few HD programs available in my area. I had a friend over the other night and was ask a question that I have always wondered about but never ask anyone myself. Why do HD broadcast have grey bars instead of black bars like wide screen DVD's? It really is far more distracting than the standard black you see with the DVD format. Is it a part of the electronics or is it in the signal itself? Any info would help. I hate it when someone ask me something about my system that I can't explain

Thanks in advance
