HD-RPTV and "Upcoverter" DVD Players (confused)

[wolfsrun]

I recently purchased a Mitsubishi WS-55813 and am upgrading my other components around the television. Right now I am looking for a good DVD player under $300. Is there any reason to go with an "upscaling" DVD player (such as the Samsung HD-941, Sony DVP NS-975V, panasonic DVD S97S, or Toshiba SD-5970)? My understanding is that the Mitsubishi upscales the signal to 1080i (it does not support 720p). If that is the case, is there any reason to buy anything other than a good 480p Progressive DVD player? (and can someone make a suggestion in my price range)

Also, for those of you who are in the know with the Mitsubishi WS-55813, is there a particular setting I have to enable to cause the upconversion, or is it automatic? Right now I have an old Sony 480i DVD player and although the picture is quite good on the Mitsubishi, I haven't seen anything in HDTV yet.

Thanks!

No clue about the Mits, however I have a Hitachi 51S500 RPTV and it "does not" natively display 480p, (read picture pretty much sucks), thus an upconverting, (1080i), player is the way to go.

My problem is trying to find one that can not only upconvert, but play Divx too
