As a general rule , it is better to use the DVD player's scaling/deinterlacing capabilities or use the display's scaler/deinterlacer ?? I suppose it depends on the type of processor. (better ones like Faroujda) Also, can you mix and match ? For example , let's say the player has HDMI ouptut and can upconvert to 720p. Can you let the player do the deinterlacing and let the display do the scaling ? Or vice-versa ? Let the player do the scaling and the display the deinterlacing ? When you output over HDMI do you have the option of selecting 480i,480p,720p,1080i ??
