Hi all... I bought a TC-P60S30 almost a year ago (in August) and have not been very awed by the picture. Especially with BDs and especially when these BDs look better on other people's crappy Visio TVs (maybe they're not as crappy as I thought

).
Anyway the picture is too GRAINY for a 1080p picture (BD movie, HD feed, etc). I'm using a PS3 and have tweaked the settings so that it looks a bit better, but it's not clear like I know it should. I have not been blown away by the clear picture I should see from my Avatar movie that I see on my buddy's TV....
I've called customer service and after a month (of troubleshooting and getting the run around) have been told they don't think it's an issue but gave me a service number to call but not to expect that the warranty would cover it (because they don't think their's an issue). This picture does not look better than 720p, even when it shows it's a 1080p signal. What gives? I want to push to get a tech out, because I cant' buy that this is just a grainy, sub-par pix... maybe I'm being naive? Sheesh...
Oh, and I did turn CATS off when the brightness started freaking out.
I can get a Geek Squad person to come out to calibrate for free (prior to the warranty ending).... can he/she unlock some magical picture setting that will make the graininess go away? I'm just not sure...
Thoughts?
