[mythtv-users] Some problems with myth/ivtv - workarounds?

I've also had good luck with just reloading the ivtv kernel module (rmmod
ivtv && insmod ivtv -- in the most basic form)

I've even setup a crontab to reload it every few hours (assuming nothing is
reading from the video input at the time... which can be checked using lsof
and grep'ing for video0/1/whatever)

These are all ivtv problems, and don't too much about pointing them out
at the ivtv list, first of all most of them read this list and second,
they know about them.  AFAIK these are problems related to firmware and
modules loading and race conditions and...  Basicaly _really_ hard to
reproduce.  The good news is that if you reboot and make sure it's
working then they normally continue working.
