avfan, i don't know. my panny is set to full mode all the time because it is receiving the source singal through its hdmi board and it can only be on full when using a hdmi source. i'm just wondering since the panny upconverts 480 to 768p or whatever, then an upconverting DVD player like the Oppo would not be necessary since the plasma is upconverting the source. that is what i'm asking. is an upconverting DVD player necessary when watching a standard DVD on a HDTV since the TV is upconverting? i have a ps3 which does not upconvert so i was thinking of getting an oppo from my old dvds. would there be any improvement with the OPPO given the Plasma TV?
