I should add that when I run mplayer from mythfrontend for a video
file that mythfrontend can not play, only mplayer gets the remote
buttons, not the underlying mythfrontend.  I do not know how that
works, as if I run irexec in parallel with mythfronted, they both see
the remote buttons.

Another alternative for changing radio stations is to add them to
MythTV as channels and use a channel change script to send the change
station commands to your radio service.  I have that working for my FM
radio scripts I use with my mothers PVR-150 FM tuner.
