It appears to be a KOAT issue. I have a friend with a Sony that I rang up; same issue. I have a Sammy 151. I note that it affected the game and the commercials.
Funny that KOAT had no idea about the problem. You would think that someone is monitoring their broadcast with consumer equipment somewhere? Not counting us.
During the NHL and NBA playoffs, there was a problem with their picture; it kept loosing focus. I e-mailed, and got a quick reply saying they were unware of the problem. A short time later, I got another e-mail saying that they (KOAT) got an e-mail from ABC, telling them to tweak a setting on one of there devices. Oooops.
On the plus side, Soundstage last night (Tom Petty, The Last DJ) was in 5.1. IIRC, the previous shows had been in 2.0. FWIW, even the 2.0 shows were fantasic when decoded in Pro Logic.
In fact, I was not really impressed with PQ or Sound quality of Tom Petty. From the looks of it, it appears that this was shot on film. Compared to the previous shows that were shot on HD video, it had a certain "look" to it that seemed lacking in detail.
And the sound was not that great either. The bass/drums were OK, but the cymbals had a harsh quality to them. His vocals had a certain raspiness as well (OK, I know, it IS Tom Petty!).
I did have one brief incident of pixelization. Don't think I have gotten through a single episode of Soundstage without some sort of audio or video problem, minor as they are.
