Regarding the Hitachi 57s500: Do most of you use the "normal" or "warm" color temp setting for dvd viewing; I know it's a matter of taste, but just curious what you use on your RPTV. When using progressive scan to watch a dvd (I use a Panny xp30 dvd player), do you toggle to 540p or 1080i on the TV? With my eyes, I can't see a difference between the two. Theoretically, which one ought to give the better picture? Is there a still, test pattern on one of the calibration discs that you can suggest, so I can determine which setting is best? I sure can't see a difference with Moving images. Oh, and what about basic 4x3 programming--like an old TV show; this Hitachi offers me 540p or 1080i for those signals too. Thanks.
