I've had problems with the channels pixilating around the same time here in the Augusta,GA area. That is the main reason why I am considering getting Direct TV or Dish Network. Here,it is like a momentary freeze,silence,then pixilation. It happens on the HD channels & digital SD channels. I have Charter Cable,Internet,& Telephone,& about 2-3 times within the past month,they all went out at the same time. They come back on,but it is very frustrating.Even though Charter doesn't have the channels that Comcast or Knology(the cable options in other parts of the county I live in & Augusta,GA) have,it does carry a few channels that the other two don't.I also want to put up an outdoor antenna for OTA coverage when Charter acts up.
Oh yeah,our pixilation problem has been going on for months now.
