Hmm, I wrote a longish post yesderday explaining a bunch of different ways pixelization happens and how it is sometimes not your local providers fault but could be a problem upstream as most providers buy all their channel signals from multiple sources, not just one. ie, local weather is clear but the originating source feed in (wherever) is experiencing sleet or lightning near it's uplink dish.

I don't see it anymore so I must have pulled the old "forgot to hit Send after hitting Preview" stunt.

With great power comes Awesome irresponsibility.
