90% of the time my picture is great. But 10% of the time (and most of the time on UPN), the picture looks like a PC monitor set on 256 colors. A face on the screen should be made up of many continuous shades of color. The faces on my TV look like a bulls-eye with two or three solid rings of color. Is it a software problem...as if the compression is set too high? Is it just me? It happens way too often and may send me back to cable. Anyone have any similar experiences and/or solutions?
