My question is "why purchase an upconverting DVD player?". I have a $900 HDTV that has 768 lines of horizontal resolution. Any source that is provided to the TV must be scaled to this. This scaling could be up or down. The input signal may also need to be de-interlaced, etc. DVD player outputs 480 (540) lines, interlaced or progessive. Why would I buy a $100 upconverting DVD player to convert the 480p to 720p when my TV does that conversion anyway and I would expect the scaler in the TV to be better than that one in the DVD player. I understand that the upconverting DVD players give you full digital link to the TV, but there is still a D-A conversion happening before display. Please advise.

That is a distinct question from upscaling players. If you're going digital out to the display, presumably it stays in digital to the display. Depending on the type of display, it may stay digital the entire way (as in DLP).
