This can be kind of hard to setup. You need to use prog = irexec in 
lircrc, the script you want to run must be executable by the user 
running it (in this case mythtv), and you need to have irexec be 
launched as part of the user desktop startup process. You can't launch 
irexec before starting X. I have a script /usr/local/bin/launch_irx.sh:

  killall -wq irexec
  irexec &

that runs when fluxbox (my WM) starts for mythtv. If all those are set, 
it should work. I would verify that your restartfrontend script also 
does what you want.
