I have a progressive scan tv that takes a 480i signal and turns it into a 480p signal. It does a good job at it when the quality of the input signal is good, but often the source originating from the tv station itself is poor then the picture just gets uglier and full of artifacts.
What is good about progressive scan, is if you have a progressive scan component input and feed a progressive scan signal from a DVD like the Sony DVP-S9000ES, then the result is just amazing and you gain 43% more in resolution because you have to divide the amount of progressive lines you have by 0.7 to equate the interlace resolution. That is why Panasonic claims that their 720p HD equates Sony's original 1035i HD... 720/0.7=1028

I may be wrong, but I don't believe that progressive gains any resolution over interlaced from what I've read. It improves on image by removing (actually, by not adding) artifacts attributable to interlacing the image. However, you are still left with the same number of scan lines using a progressive scan approach -- it simply delivers them as a single frame instead of two, interlaced frames. Thus, 480p and 480i have the same "resolution" but one is prone to certain artifacts that the other isn't.

I am going to get the Sony DVP 9000 ES to replace my Sony DVP 7700. I want to play with SACD anyway.
I wish I knew how to tell if the Mitsubishi WS 73903 will accept progressive scan. It does have HDTV capbility, and it does have componenet inputs (which I send directly from the DVD player).
In any case, no sense in turning over the TV at this point to get the Mitsubishi WS 73907.
Thank you for keeping things reasonable for me.

  I have the same TV and I don't believe that it does. The picture with a regular DVD is pretty amazing though, as I'm sure you know.
  - I agree the picture is great as it is Samir 06:13:20 12/12/00 (0)
    And after I get the progressive scan DVD player, I will always wonder how much better the picture could be with the ws73907 that CAN accept progressive scan.
    But for now it seems it is a great picture, and I will just keep it as is.
