Last night watching Criminal Minds out of Sacramento channel 13 in the middle of the program for about 2 minutes I was getting severe pixelation and the sound was distorted. I switched to the OTA HD channel and to my suprise the problem was also there. This again happened at the end of the program. I thought that maybe my dish might have been out of wack so I turned to OTA and it's also happening. What can be the cause. The rest of the program was crystal clear. This also happened on the show following Criminal Minds, CSI New York although it happened to a lesser extent. Anyone have this problem or answer?
