I have a Toshiba 51HX83 and a Panasonic DVD-S55 DVD player. I have always had the tv fed through the component video cables and the progressive scan of the dvd player turned on. Lately I have discovered that my picture quality is better with the progressive scan off. I then discovered that my s-video picture was better yet than the component. Does anybody have any ideas as to why this is? Both sets of wires are higher end wires.
