You say "Running mythtv-setup, removing all encoder cards and adding them again fixes this." Is this a permanent fix, or does the problem recur if you reboot?
If this is only a fix for that boot, there are easier ones. Anything that causes mythbackend to force a reschedule is a temporary fix (this includes restarting mythbackend, or just marking a new show to be recorded).
Barney - could you clarify your comment for me?
