This happened to me last night, with the same symptoms.  I solved it
by following the instructions in the Myth documentation
(http://mythtv.org/docs/mythtv-HOWTO-22.html#ss22.4, under "MySQL
database is corrupt"):

If you have reason to believe that your MySQL database is corrupt,
execute the following commands to attempt to repair it.

NOTE: Ensure that there are no programs accessing the database while
you attempt to repair it. Make sure that all backend and frontend
programs have exited.

mysqlcheck -r -umythtv -p<password> mythconverg

Then I restarted mythbackend and everything was right as rain.  (I'm
also going to put my master backend on a UPS and have it trigger a
graceful shutdown to handle future power outages.)
