Honestly this is making me laugh... A DVD player's output resolution and its input resolution are two totally different things. Yes it can display 720p via re-sampling a 576i/p (720 x 576), 480i/p (720 x 480) source video but it can not decode (read) a source video of 720i/p (1280 x 720), 1080i/p (1920 x 1080). The only players capable of decoding (reading) HD material (720i/p, 1080i/p) are Blu-ray or HD-DVD players. To be honest, if you have a DVD player that has a HDMI connection and leave it to output 576i/p, 480i/p, connecting it to a good quality display there wont be a major difference compared to when you set it to up-convert to 720p/1080p. See, the thing is that it's very hard to find a DVD player with a HDMI connection that doesn't up-convert. So people are led to believe that it's the up-conversion that yields the quality improvement but really it's the HDMI connection that brings the biggest improvement. The reason is that it's a digital connection. DVD = Digital Video--->HDMI = Digital Connection--->LCD/Plasma = Digital picture. DVD = Digital Video--->Component, Scart, S-Video, Composite = Analog Picture--->LCD/Plasma = Analog Picture must be converted back to digital picture. If this still isn't making sense go back to post 1!
