Mabey you guys can correct my whole understanding of this upconversion.
My guess is you would only need to upconvert through your receiver if your DVD player is older and only supports composite or S-Video. Now depending on your TV's native resolution it would be useless to upconvert to 720p or 1080i if you TV only displays 480.
My Toshiba Plasma has a true HD picture at 720p, my Denon 3910 can upconvert to 720p or 1080, should I leave the DVD player at 720p, I'm thinking if I put it at 1080 the TV will just downconvert it back to 720 which will probably degrade the picture overall. the same goes for my Xbox-360.
This is just my understanding, please correct me if I'm wrong.
