I have a 50H82 Toshiba and I have to say that the picture on DVD (component?) input is fantastic. My problem occurs with either sat or cable. On cable I resign myself to the fact the picture will always be substandard but the sat I think should look better than it does. If I use an s-video input to the tv from the sat should the picture be better than the composite (RCA) video? My understanding is the line doubler in the tv is not active when fed by s-video only by composite (RCA)video. Is this correct? I would think that a $3000 rptv could process the signal better than a $50 sat reciever. BTW-Not sure if I have component or composite right.
