In my experience Mythtv 0.24 > 0.26 this is normal operation.
If the frontend is not used from boot the backend will start and stop 
the machine as required.
Once the frontend has connected the machine will obviously not shut down 
until the frontend is closed.
When the frontend is closed the machine will shut down if no recording 
is expected within the time limit.
If the backend is recording when the frontend is closed the machine will 
shut down when the recording has finished.
However if the backend is not recording but has a recording pending 
within the time limit, shutdown will not happen.
So if I have a recording pending last thing at night after finishing 
viewing I reboot and things work fine:-) .
