I see pixels when there is a lot of motion on my plasma tv. How do I get rid of it?

I have a Panasonic TH-50PX700U plasma tv connected to Directv. I am sitting here watching a football game on NBC HD. Everytime there is a lot of motion on the screen I see pixels. Then when the motion slows down or stops, the picture returns to normal. How do I get rid of this problem? Also, are there optimum settings for my TV instead of what Panasonic programs in at the factory?I see pixels when there is a lot of motion on my plasma tv. How do I get rid of it?There are custom settings for a 50" Panasonic plasma (last year's model number, but settings the same) at CNet.com and AVSforum.com, as part of a review of the set. I have a 50" and the settings were a help, but needed tweaking for my preferences. Search Panasonic setting here and you'll come up with a post of mine, in the last month, where I set out all the suggested settings.I see pixels when there is a lot of motion on my plasma tv.
