I've seen this. It happened in a strangely encoded movie
I recorded a few weeks ago. And it happened when switching
from the cable company add back to the network stream.

I kept the recording, but I haven't had a chance to look at
it yet. My guess is that there is an aspect ratio or resolution
change we don't handle for some reason.
