I am kind of confused about all of this upconversion stuff. Can someone point me in the right direction or give me some links about it? Like my question asks, why get a very good progressive scan dvd player if your hdtv upconverts to say 540p/720p/1080i? I know why I got a progressive scan player. Simply put, my JVC interlaced dvd player looked terrible on my 64 inch widescreen. Once I switched to a good progressive scan dvd player it was a night and day comparison. Is that because my set does not upconvert well? DirecTV signals do not look that good. I can see a ton of scan lines. Is that just because of DirecTV or is my tv not doing a good job of upconverting the 480i image? I have also heard that it is a good idea to get a very good interlaced dvd player for fixed panel displays such as DLP/LCD AND LCOS and let the hdtv itself do the deinterlacing. Is this true? Thanks for the help.
