I currently have a sony kp-51ws500 with a dish network 501 dishplayer receiver with s-video going in, i added a dish 6000 hdtv receiver with component outputs to t.v. the 501 s-video and the 6000 sd with s video out seem to have just as goos if not better picture than the 6000 with component out. am i doing something wrong. i was thinking of getting the 921 with the hdvi outputto see if that makes any difference. thanks, pajer
