I’ve noticed that Comcast has not been living up to expectations lately. All too often the picture becomes garbled, in a pixelated way, or freezes, with or without the use of a cable box. Last night it did it just as Stephen Colbert (in the 8:30 rerun) was talking about running for PRESIDENT! (in South Carolina) For a total of 10 minutes most of the channels were frozen, while others worked fine.
