I've got digital cable and HD channels through TWCable. Every once in a while, the picture will have a quick moment of pixelization. It will look like a bunch of squares larger than the resolution it should be (on both 480 and 1080). Is this due to bandwidth problems in the cable transfer? It usually only happens when there's lots of motion on the screen. So if I'm watching PBS' scenery feed, it never happens. But yesterday I was watching basketball and sometimes when they were zoomed in on someone and he moved quickly, there'd be a moment of pixelization. Wassup wit dat?
