This is only my opinion.... The digital pixelating on standard definition is a known flaw with the 622 and 722. Every VIZIO I have seen does amplifiy the distortion more than others. The only TV that does the best job of mastering SD is OLEVIA. I don't know why so don't ask. Out of 10-15 OLEVIA TV's I hooked up the 622 and 722 to look awsome in both SD and HD.
Case in point, I had a customer in Sun City West that had a 52" SONY flat panel. After hooking up a 722 with HDMI he pointed out the pixelating on SD. TNT and LifeTime was the worst, I went back the next day with my own HDMI Monster cable from my own TV to his house. No change. Swapped out the 722 with another and no change. Customer returned the TV to Best Buy and called me back when he bought a VIZIO, It looked a little better but he still was not happy. His neighbor had a OLEVIA 48" with a 622 in place and SD looked great. So somehow he returned the VIZIO and I got the call to go back. After lugging the new 52" OLEVIA from his car to the living room I hooked the 722 up with HDMI and it looked AWSOME! All of the standard channels did not pixelate and the HD was even better than the Sony HD.
This is tru with every OLEVIA I have seen, Not sure why but I have never seen a bad picture on the OLEVIA's.
Hope this helps!
