The content on the DVD and BD may be that bad. I've taken such content back to the PC or another machine/display and played it frame by frame and it was bad from the media. I don't have a cure for that. But if it's not that, look at any image processing and reduce or turn it off.
Has anyone experienced problems with major pixelization when watching fast motion sequences. The picture is perfect until something comes whizzing by-like watching Nascar. I'm using ATT Uverse. I tried playing with all the settings, different HDMI Ports and Component Video and same problem. This is supposed to be a 120hz TV. It doesnt seem as bad when watching from anything but the ATT Box. Just curious if anyone out there has the same 6000 series Smart Tv and using AT&T.
