I have a c.6 year old mythtv database. I recently upgraded from Ubuntu 10.04 to 12.04. This brought a MythTV upgrade from 0.24 to 0.25, which went well.

Today, all my recordings have disappeared. They still exist in the /var/lib/mythtv/recordings folder, and the 'M' key in the Watch Recordings page says that there are 201 recordings available somewhere, but they will not display. See screenshot:

Changing the filter does not remedy the fact that there is nothing shown in the lists.

My Upcoming Recordings screen says that there are no rules set, but my list of previously recorded shows is still there, and has an entry from as recently as 3am today.

mythbackend --printsched gives the following:

        The response to MYTH_PROTO_VERSION was empty.
        This happens when the backend is too busy to respond,
        or has deadlocked in due to bugs or hardware failure.

Things I have tried so far:

  • restart the backend
  • restart the frontend
  • run mythtv-setup and check database passwords and IP addresses
  • change the frontend setting for backend IP from localhost to 192.168.1.2 (the backend/frontend's IP)
  • run optimize_mythdb.pl

Other suggestions appreciated.

As you just upgraded to 12.04, I would also recommend adding the Mythbuntu Repos and updating MythTV to the latest 0.25 build as there have been many fixes.

I enabled the updated repos in Mythbuntu Control Centre. No joy, even after a backend restart. After a computer restart, however, it was fixed. I don't know whether the updates or the restart cured it, but I'm awarding the answer anyway. –  nimasmi Sep 26 '12 at 22:26
