Is anyone else seeing a flashing on Comedy HD (275, Victoria BC). I see it both live and on my Gateway's recordings of two shows (Colbert Report and Corner Gas). For a single frame, exactly half of the screen has a pattern flash over it. It happens about 10 times per 1/2 hour. Sometimes it's whitish, sometimes it's blue or purple. Sometimes it's the left side, sometime right side. It happens during shows and during commercials.
I can rewind and it's reproducible.
Here's it happening
then the next frame is clean.
