Thanks for asking this question. I was afraid I might have some tree problems. It's good to see other people are having the same issue. In my case I'm seeing it on WMAQ HD.

You can try mike@allamericandirect.com. I haven't tried that e-mail in about a year. He was the man in charge at the time, and helped me fix a billing dispute that the CSR's were clueless on.

days on the HD channels. The picture will freeze then in the process of returning it goes thru a solarization phase before it returns to normal. I also sent an email to Mike, but haven't had a response.
