Ignoring the fact that on most of the appliances (at least STBs and 
such...), when you hit the power button it does little more than shut 
off the display output...

I'm pretty sure it is doing the same thing--the difference being that 
before we exit, it sends the dbus command to shut down your system, then 
it starts to exit, but dbus rips the entire system out from under us 
before we finish exiting, so...

You can use a script, but you almost definitely haven't configured a 
script and your distro is almost definitely using dbus.

Try writing a script and configure MythTV to use that (instead of the 
"let's use a dbus shutdown even if the user hasn't configured shutdown") 
and put in a delay (or some kind of poll to see when the frontend 
finally finishes exiting) and see if it works that way.  If so, you can 
use that as a workaround for MythMusic's requirement that you exit 
mythfrontend properly and/or a workaround for the fact that dbus 
shutdown doesn't let mythfrontend exit properly.
