I am watching the Ryder Cup on NBC HD but every 10 minutes or so the signal gets all goofy. Really ruins it for me. I am trying to determine if this is something that is going on with NBC's signal. My local station (WPXI in Pittsburgh) or on my cable system. Can someone watching this OTA tell me if they see the same thing? This has happened the last 2 Saturday's at this time. The last 2 times it ruined my watching of the Notre Dame football game. I have not seen this at any other time than Saturday afternoon. It is starting to really tick me off. And if it is coming from my cable system I will be looking to get my antenna system set back up.
