Go through the archives, look for a message with a subject something like "Misc.
tips and tricks for RedHat + ivtv users" posted by me.  I posted it 3-4 days ago

for Input/output errors from /dev/video0, and if they are detected, will stop
the backend, unload and reload the driver, and restart it.
