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.
