Samsungs dvi port is digital. The only way to do what you want is to get the $400 Geffen DVI to VGA conversion box & then attach a VGA to Component converter as well to get the component video feed. From what your describing it sounds like you have an analog dvi to vga converter(like the kind you get with graphic cards)-that wont work with the 931. The analog converter will work with the momitsu dvd player-that had an analog dvi feed. IMHO, for you, its not worth it either way. The big benefit with the dvi players it to get a direct digital path(and 1:1 pixel mapping) with a digital monitor(DLP, LCD, LCoS, or Plasma)
