I've run into this. I believe what happens is that the mythbackend starts before the user mythtv autologins to the box, so it's before mythtv assumed ownership of the console devices - including /dev/video0. That's why a restart fixes the problem - you're restarting the backend AFTER mythtv logged in, and so there's no permission issues. I think you can find the indicator in the mythbackend.log file, something about permission denied when opening video0. My fix was just to have the backend restart (as root) in mythtv's login sequence. HTH! Dan
