As far as I know no matter what signal you send to your TV it almost never displays it that way. It will scale it to something. My CRT RPTV upscales it all to 1080i. whether you send a 1080i or 720 HD signal or a crappy VHS signal through the antenna input. Same for many LCD/DLP who always display at 720p or a derivative of. So on which will a DVD look better? of course this is theoritically assuming a good scaler in the units. or if there is a good one on your DVD player which would be best?
