Just to clear things up John, my present set is a Toshiba 42H82, rear projection TV. I am considering getting a new TV, which would be a DLP (Samsung or Toshiba, probably).
So, are you saying that all DLP/LCD/Plasma TV's upscale to 720p or 1080p? If that is so, then why would anybody buy upconverting DVD players? Also, if you have a fixed pixel set, have you ever compared the two methods?

Thank you!
