 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.

Regards,

Dave

 I am having issues with the PVR-500 (3 of them with identical symptoms actually) that include a distorted picture and the "Error opening jump program file buffer" problem. Could all of those in this thread please check to see if there is a coinciding entry in their syslog like 

 ivtv0: Encoder has died : ivtv_serialized_open 
 ivtv0: Detected in ivtv_serialized_open that firmware had failed - Reloading 

Yes, I've got that in my syslog:

Sep 23 15:45:53 nslin01 kernel: [194952.355339] ivtv0: Encoder has died : ivtv_serialized_open

Sep 23 15:45:53 nslin01 kernel: [194952.355344] ivtv0: Detected in ivtv_serialized_open that firmware had failed - Reloading

Sep 23 15:45:54 nslin01 kernel: [194953.404361] ivtv0: Loaded v4l-cx2341x-enc.fw firmware (376836 bytes)

Sep 23 15:45:54 nslin01 kernel: [194953.470965] ivtv0: Loaded v4l-cx2341x-dec.fw firmware (262144 bytes)

Although it coincides with a quick mplayer test that I did which didn't show the picture distortion.

Regards,

Dave.
