It proved to me that I'm going to be very happy with this set. Avatar on this screen is a dream come true. So far no problems whatsoever. FWIW my little LCD was a Samsung, and I loved it so much this set is also a Samsung. They make great tv's and yes I am loyal if you treat me good.
I believe I have it fully burned in and I have nothing to say but wow. The image quality is a dream.
And don't get me wrong, Vudu HD is very very good, it gets you to 100% of most films, but Avatar on Bluray is pumping some serious data rates. I could see Vudu HD is no slouch though, definitely good enough for most movies that you would think you're watching a BluRay. I will say this, Vudu HD is definitely better than DVD by a large margin.
