[mythtv-users] Scheduler failing...

I'm having a very strange mythtv problem. I've found a similar
sounding problem in the mailing list archives, but the solution is not
The problem is that the scheduler does not seem to be running. I have
guide data. I have shows asking to be recorded. But there is nothing
actually scheduled to be recorded. This seems to be able to be fixed,
until I next reboot, by forcing mythbackend to reschedule.
I'm running mythtv on ubuntu jaunty on a new box. I used this FAQ
entry to copy the data from a previous ubuntu intrepid install:
If I boot the machine, then `mythtv-status` shows no upcoming
recordings, and neither does `mythbackend --printsched`. `mythbackend
--testsched` however will print a bunch of recordings (but seems to
leave the actual recording schedule untouched). If I run
mythfilldatabase then this seems to force a reschedule and then
everything is fine until I next restart the machine. If I hit record
on a program, then myth will reschedule and everything will be fine.
I can then change that program back to not record and everything stays
fine. On restart it all falls apart again.
I tried modifying /etc/init.d/mythv-backend to call mythfilldatabase
immediately after starting mythbackend. This did not fix the
problem. I found that strange, because I thought that just asking for
a reschedule would fix things.
I then tried adding "(sleep 10 ; mythfilldatabase) &" in /etc/init.d/
mythv-backend immediately after starting mythbackend, and that did fix
the problem (although this seems to be a little intermittent).
So I then wondered if there was a race condition with something that
myth was relying upon. I tried adding a sleep 10 just before
mythbackend was started. That did not fix the problem.
If I run MFD and everything is fine, then rebooting causes the problem
to come back. Simply restarting mythbackend does not seem to cause
the problem to come back.
I wonder if there is a database schema issue? (but I don't know why
forcing a reschedule would help in that case...) At this point I'm
P.S. I think my next plan is to use mytharchive to archive the
recordings I want to save, and then just wipe out the mysql db and
reconfigure from scratch. I find setting up the channels table really
annoying now though - what happened to the channels page in mythweb?
It was much better than either the setup program or kmysqladmin. I
want to edit all the channels on one page and then commit once when
