I may have mis-communicated and/or mis-read. If you restored
the program table sans "The Nanny", the badness may actually
be somewhere else as you've pointed out. "delete from program;"
then run mythfilldatabase while there are 0 entries in the
program table so that it pulls in entirely new data. The
reason I suggested dumping the data was for later analysis
in case this turns out to be the problem.

Run mysqlcheck (if you haven't already =) in case there is a
One thing that can happen is that a bogus entry can show up in
the 'record' table. This has happened to at least JAC, David and
myself. Normally it just screws up the Recording Priorities page
but maybe you have a bad entry that affects the scheduler. Go to
the priorities page and see if there is an entry with a blank
title, unprintable characters, misalignment where there is
garbage in all columns, or if you only see a few things when
you know there should be several more.
If so, look at "select * from record;" to see if there are NULL
titles, zeroed out times or dates, bogus string in the "profile"
