Get the script from http://www.mbwcomputing.net/frontend_idle.sh
It uses frontend_shutdown.pl perl script available from mythtv wiki.

Screen saver doesnt activate whilst you are playing something, but if 
playback is paused, it will go to screensaver.
I used the frontend_shutdown.pl script to close the FE gracefully, I 
guess you could ACPI Sleep instead.
