I've read that the key to getting the best PQ on digital displays (DLP, LCD, LCoS, Plasma) is to insure that you're using a DVI cable and getting 1x1 Pixel Mapping. I'm guessing this means knowing the native resolution of your display and then getting a DVD player that can hit that resolution exactly to avoid multiple scaling. Since most fixed pixel displays run at 720 or 1080, my first thought was you'd have to get a upscaling DVD player. But this brings us back full circle: which device has the best scaler (just like the old X prog player vs. Y HDTV experiments). One exception might be a dedicated non-HD Plasma EDTV running off a standard DVI prog DVD player for HT only. No HD, but you would get DVI + 1x1 Pixel Mapping without any scaling.
