most often even if the driver think that the reload was successful

I do not pretend to understand how the ivtv driver works or what
causes this error message but is there any thing I can do to try to
track down what is causing this?

I'm seeing the same problem. It started when I switched to MythTV
0.25. I had a PVR-250 and a PVR-500. I originally thought the problem
was failing hardware and replaced the 500. The problem just jumped to
the 250. I have since put the 500 back and am now using a PVR-500 and
a HVR-2250. I just watch the logs for those messages and reboot soon
after they appear.

Thanks Ken,
I have seen numerous posts about problems that include this error on the
PVR-250,350 and 500 cards and many seem to agree that the problem is
failing hardware. I have 3 PVR-500s and have tried all three and get the
same error on all of them. I can also remove and reload the ivtv module
and fix the problem in 30 seconds and get a perfect recording. In fact I
have written a script that watches the syslog for the Encoder died
message and reloads the ivtv module. My recordings are now all perfect
although some are missing about 30 seconds from the beginning. I do not
believe this is a hardware failure but do not know how to proceed with
trouble shooting.
I can say from looking at the logs that when the ivtv driver sees a
problem with the firmware it tries to reload it. My script kills the
backend, reloads the ivtv module and restarts the backend so I end up
with a part A and B of the recording allowing me to see whether the
reload was really necessary. While the ivtv module usually reports
successfully reloading the firmware in reality more than half the time
the A part of the recording which is started after ivtv reloads the
firmware is corrupt and the B part after my script reloads the ivtv
module is always fine.
Paul
