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.

I have had two Panasonic plasmas and never noticed the problem you describe. Extremely fast motion may be somewhat blurred with a plasma display, such as the faces of the fans in a stadium, but not to the extent you describe. You may have a dish that is not fine tuned to the satellite. If not, there is a problem with your display.
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.
