I cheated, and just put a 30 second delay into the service shell script before mythbackend starts, and I have had no problems since.  :-)

If you choose the simple method above, you may be able to get by with less time.   
I don’t start and stop the service very often( maybe once a month) so 30 seconds is no big deal.
