I have been having this same problem for about 2 months now. I have to
restart MythBackend and everything works again for .5 day to 3 days,
then next time you go to check scheduled programs, you get nothing.
It is not necassarily after a mythfilldatabase update, as I usually
don't run mythfilldatabase everyday. Sometimes waiting a week to run
it, when I see the scheduled programs getting low.
I have tried using MythBackend in debug mode, but that doesn't appear to
log anything that I found useful, no error messages, or anything.
If you find something please let us know.
