This sounds a lot like the issue that hit GNOME users a while back where 
mythbackend was started before the network was set up (due to GNOME's 
network manager) or the one that hit upstart users where mythbackend was 
started before mysql was started.  However, in those cases, mythbackend 
would start just fine once the system was up and running--just wouldn't 
start from the start script on system start.  Have you tried just 
starting mythbackend after the system boots (without restarting mysql)?
