I have this problem when streaming video where it gets all blocky with weird colors, like in the pictures below. It doesn't happen all the time, and it happens much less than it used too. It doesn't really happen at all with Youtube or Vimeo, but with other things it sometimes does. I have MLB.TV, and whenever I turn it up to HD quality, it does this, which is really annoying. It still moves, you can vaguely make out the shapes of people, and the audio works fine. I have tried updating my graphics drivers, I've tried Chrome and IE, and I can't get it to stop. Any help would be appreciated! Thanks!
