Plasma motion artifacts with satellite TV


I have motion artifacts with sports (hockey, people moving)
on my Sony TS2 plasma TV and satellitt TV. Is this a defect needing repairing? I see much larger blocks of pixels when it blurs.

Thanks for your help. I guess its not TV but satellite (dish network/svhs) connection because yesterday I had many satellite connection errors and problem occurs intermittently. (today tv worked well).
There's no component hookup, this is standard def receiver.
Interlaced source (standard television) is not good. But looks good with dvds. I got this TV really cheap 2 years ago online and it took 1-2 months to received- maybe slightly defected tv. Maybe high def receiver will look better.
Samuellaudio,

The problem you describe sounds like a signal degredation issue, not a display issue. I had similar experience with digital cable and the cable company came out, checked my signal and promptly replaced the cable coming into my house. The pixelization ceased as soon as the cable was replaced.

I have a Plasma display and don't see any serious motion issues.

Enjoy,

I should have been more specific in my response. Extremely fast motion may be somewhat blurred with a plasma display, such as a camera pans the faces of the fans in a stadium, but not to the extent you describe
