I recently purchased a Pioneer Elite pro530-hd, and I'm still climbing the upslope of the learning curve of HT. The pro530 seems to upconvert all 480i inputs. You can select from either 480p or 1080i to watch any input. I've read multiple times that the Elite monitors have a very good de-interlacer built in, so I'm going to hold off on upgrading my non-prog dvd player for now (I'm working toward upgrading my receiver first). My question is, should I have my tv upconvert my non-prog dvd player to 480p or 1080i?? Along the same lines, should I be upconverting my SD-sat input to 480p or 1080i? When I do eventually upgrade to a high-end prog scan player, will the tv recognize that, and no longer give me a display option, or will I still have to choose from 480p and 1080i? In that situation, should I just leave it in the native 480p mode, or upconvert the progressive signal to 1080i? My one question seems to have become three or four, but I'm still learning here Next step is to figure out all of the picture menu options beyond the normal things I'm used to.
