I am experiencing pixilation in the dark areas from my TV(Samsung 28inch) when I play DVD's and sometimes from Sky Digital. Also the only way I can have both the Sky and DVD working properly is when I connect the Sky into the RGB scart(set on PAL setting in the Sky setup) and the DVD into the normal scart. When I set the Sky setting to RGB there is no picture from the DVD. When I set the DVD setting to RGB there is no picture from Sky. DVD is a Philips. Help!!!!!!!
