    I have TWC and in the past year have begun to see problems on ABC-HD prime time shows and occasionally FSN-HD.

    The picture fluctuates from sharp to what I can only describe as a spider web type artifact over the entire screen. It comes and goes every few seconds….almost like it is inhaling then exhaling…or a filter trying to kick in or something.
    At first I thought it was my HDTV (40 in Mitsubishi LCD)but it never happens on other channels…and never on local ABC news or during commercials.
    It did show up on a NHL hockey game on FSN-HD on Friday night, but was not evident on a hockey game Sunday night.

    The good news, I guess, is that it’s
    not my HDTV, but seems to have to due with the transmission from the network or from TWC.
    I also notice that during some sports,
    there are some cameras being used that are not HD..only SD as the PQ is evident, even if the image remains on the screen as 16×9.

    Any thoughts?

    All of what you say is true and i ask this: Is the present system designed to accomidate changes that will result in better picture quality and why was this system adopted knowing that serious flaws existed and all that i hear is “that great digital picture”. Most of the standard definition channels are very poor and I feel sorry for the people that bought a $60 set top box as the analog signal was better than the poor digital signal.

    I know this if off topic but I am seeking into starting my own weblog and was wondering what all is required to
    acquire set up? I am assuming possessing a
    blog site like yours would cost a pretty penny? I am not really web smart so I
    am not 100% positive. Any recommendations or advice might be greatly appreciated.
