In mythtv-setup under General, the page 'Shutdown/Wakeup options' has a 
field 'Pre-shutdown-check command'.  You can enter a command (usually a 
script) which should be run when the backend is ready to shutdown. 
Depending on the value returned by the command, the shutdown can be 
prevented or allowed to continue.

The following page deals mainly with getting your system to wake up at 
the right time but there's also a bit about shutting down:

(search for 'checklogin.sh' and 'TurnOff').
