Alright I am having some difficulty understanding something about progressive scan. Here's an example of what I don't understand. Say I hook up a DVD player with progressive scan to a Dell 3200MP projector. The projector has compatability with 480p, 480i, 720p and 1080i. So what does the projector project? Does it project in 480p or 720p? I guess some questions are: 1. Do DVD players only send out progressive signals and then its the display device to bear that signal down into either 480p or 720p? 2. Does the display device do this automatically or can I set it to the signal I want. 3. Is it the DVD player that sends a 480p or 720p signal? In which case can only certain DVD players send in 720p or is there a setting on the DVD player to send a 720p signal?Matt On a side note, which is better, 720p or 1080i?
