I just saw the same thing this morning on my PVR-350. I'm
running <br>
Fedora 17, kernel 3.5.3-1, MythTV 25.2-1 from RPMFusion.<br>
<br>
I somewhat suspect it's a leaky/bulging capacitor I found
on my PVR-350 <br>
today, however. The card is 7 years old, after all.<br>
<br>
On the other hand, other flaky behavior with the ivtv
driver re-loading <br>
itself and causing the myth backend to no longer use that
tuner do <br>
coincide with my upgrade at the beginning of the month for
Fedora 17.<br>

<p>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.</p>
<p> </p>

I am having issues with the PVR-500 (3 of them with identical
symptoms actually) that include a distorted picture and the <font
color="black" face="Verdana,Arial,Helvetica"><font
color="black" face="Verdana,Arial,Helvetica">"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 <br>
<br>
ivtv0: Encoder has died : ivtv_serialized_open <br>
ivtv0: Detected in ivtv_serialized_open that firmware had
failed - Reloading <br>
<br>
<br>
</font></font></div>

<p>Yes, I've got that in my syslog:</p>
<p> </p>
<p>Sep 23 15:45:53 nslin01 kernel: [194952.355339] ivtv0: Encoder
has died : ivtv_serialized_open</p>
<p>Sep 23 15:45:53 nslin01 kernel: [194952.355344] ivtv0: Detected
in ivtv_serialized_open that firmware had failed - Reloading</p>
<p>Sep 23 15:45:54 nslin01 kernel: [194953.404361] ivtv0: Loaded
v4l-cx2341x-enc.fw firmware (376836 bytes)</p>
<p>Sep 23 15:45:54 nslin01 kernel: [194953.470965] ivtv0: Loaded
v4l-cx2341x-dec.fw firmware (262144 bytes)</p>
<p> </p>
<p> </p>
<p>Although it coincides with a quick mplayer test that I did
which didn't show the picture distortion.</p>
<p> </p>

<p>Dave.<br>

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. <br>
<br>
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.<br>
