Well, two techs have been to my house, the last one changed out the box, which didn't fix anything. A day or two after tech #2 was here, I saw several Comcast bucket trucks in my area while taking my son to work. All day long, my cable kept disconnecting, both television and High Speed internet. By 7 PM that day, after the last time my cable disconnected and reconnected, pixeling has become a thing of the past on my HDTV. I'm now getting the sharp, clear picture I should have been getting all along, since going HD. The picture I'm getting on all channels even looks better than what the picture looked like on the floor model where I bought my HS system.
If anyone who reads this thread is still having pixeling problems, that's where you see all these little square block areas on your screen and the sound stops and stutters like Barak Obama without a teleprompter, keep calling Comcast to tell them you'd like the problem fixed, that the problem does not originate within your home, and that you'd like each day taken off your bill until they get out and fix the problem on THEIR equipment bringing the signal to your home. Talk to your neighbors who are paying Comcast for cable service and if they're having the same problem, have them tell Comcast the same thing. When you start taking money out of their pockets, Comcast will listen and act.
