The prices on these sets are getting awfully tempting now...and I'm guessing they might be even more so after Christmas.... Probably 75% of my critical viewing with this set will be DVD, remaining 20% high-def once I get an HDTV satellite receiver (come on ExpressVu!!) and maybe 5% my "regular" 4:3 satellite stuff (Simpsons and Speed Channel mostly), where I can live with the "stretch" modes. So are there any known issues or problems with the 57HX83 sets from Toshiba? I did a search and learned a bit about the 540p "upconversion" and non-native support for 480p issues with progressive scan DVD - how big of a deal is that really? I'd prefer a set that actually does 480p for DVD viewing rather than processing the image further, but if it isn't anything particularly bothersome or nasty it's not a big deal...what should I be on the lookout for to see anything "off" caused by the 480p to 540p "upconversion"? And how is the set with HDTV satellite content?
