When using color stream inputs (component) am I correct in assuming that a DVD players signal will automatically go thru my RPTV (Tosh TW56x81) line doubler? If the answer is yes, is there anyway to disable it? My question stems from the fact that I currently use a Tosh 2109 DVD player and am really pleased with the results. I bought, and subsequently returned, a Tosh 4700 player because even when switched to progressive scan (switch in back of player) it wasn't near the quality of my existing player. Would there have been some kind of signal conflict? Any thoughts would be greatly appreciated.
