Here we are almost a year after my HD TV purchase, and my T-W feed for some channels is still crap. Fast moving close-ups of sports or action movies results in varying amounts of pixelating on many channels. I have had them out numerous times to no avail. I know it is not the TV, because sports on some channels(ESPN), I don't see the problem at all. Other channels(NBC), are horrible and I see it all the time.
If they are compressing the signal as some here previously suggested, they are never going to own up to it. Therefore, I either live with it, keep making them come out to be a pain in the ass, or switch to having a Wok on the side of my house(no thanks).
PS Verizon has stalled on their FIOS deployment in WNY, so I am screwed in that regard.
