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.

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.

The last two lines indicate that the ivtv driver reloaded the firmware successfully so ideally you should have had a good picture. I have been watching the log file and when I see the Encoder has died message about half the time the recording will have a corrupt picture. The ivtv driver claimed to have successfully reloaded the firmware but the picture say otherwise.
I have written a script to kill the backend, remove and reload the ivtv module and restart the backend whenever I see the Encoder has died message and this results in good recordings (albeit with about 30 seconds missing at the begining) 100% of the time. I have 3 pvr-500 cards and they all 'developed' this problem when I upgraded my backend box to Debian Wheezy and Myth 0.25. I suspect the ivtv driver is the problem but do not know how to proceed from here. I have posted this issue to the ivtv users list but there has been no response. If everyone here in this thread is seeing the same error then how about posting in my PVR-500 Problem thread so that ivtv knows there is a reproducible problem and can maybe help us track it down.
I'll check my syslog next time I get a problem picture and see if I get that error at that time.
Excuse my ignorance, but how do I get on the ivtv mailing list as I've never had the need before?
Also, could you post your script as that would be an acceptable short term fix for me.
