Are the backend and frontend command line options documented anywhere? I
haven't been able to find them on the wiki, and I noticed that --help isn't
recognised. It would be really useful to know some of the tricks.

You can force the running backend to reschedule by using this command:
  mythbackend --resched
It will signal the running backend to reschedule.

But this probably isn't your problem. You probably updated your ivtv or
v4l drivers when you upgraded, and the driver changed the enumeration of
it's inputs. Back up your DB, and then try deleting your capture cards
and recreating them and their connections to video sources in the
mythtv-setup application (shut down the backend first).
