I just saw the same thing this morning on my PVR-350.  I'm running 
Fedora 17, kernel 3.5.3-1, MythTV 25.2-1 from RPMFusion.

I somewhat suspect it's a leaky/bulging capacitor I found on my PVR-350 
today, however.  The card is 7 years old, after all.

On the other hand, other flaky behavior with the ivtv driver re-loading 
itself and causing the myth backend to no longer use that tuner do 
coincide with my upgrade at the beginning of the month for Fedora 17.

I don't think it's a hardware fault as I have this problem on 2 PVR250's in 2 separate systems. I suspect it's an IVTV driver problem as I finally got around to trying the card outside of mythtv (using mplayer /dev/video0 -) this morning and the same thing was happening, I quit out of mplayer and ran the command again and the picture was OK. I'm not a member of the IVTV mailing list, but it might be worth taking a look there to see if it's been reported.
