Had my Hitachi 51s500 for about a week now. HD signals are very good. Cable and sat are about what I expected, not good, not even as good as my 4 year old stand. def Mits 50". DVDs look poor, I do have a progressive scan player, but the pic looks grainy and the colors dull. Is there any way that this is a result of 3:2 pulldown, and if so can it be defeated. The picture is kinda film-like, but not in a good way, dull,grainy, and kinda out of focus, even new movies. Actually everything but HD looks less acurate and colorful than my stand. def Mits. Might I have a bad set or is this not the right set and or time for me to upgrade to HD?
