Is the logged in user in sudoers?

you should have a line like

%mythtv ALL = NOPASSWD: /sbin/shutdown

in /etc/sudoers. To edit that file, run "sudo visudo"

I thought there needs to be something in there. If that command returns
0, the PC will shutdown, otherwise not. Try "mythshutdown -s" which is
the default, I think.
