Yellow Screen!!!
I had that too, very strange, but I was watching the Tuesday night premier of "Fringe". At one point everything went extremely pixellated for about 5 minutes and I had a pure yellow screen in there a number of times.
AND
I had audio dropouts too. Right before every ad break, the audio would drop out for a second. In fact it was regular enough to be able to judge that an ad was about to start and start skipping. I just wrote that off as the station changing from sending 5.1 to stereo for the ads, or something like that. It was very strange.
We fought to get Fox here in Seattle for years, finally got it, and now it is less than reliable. It is just insane.
