Have you tried running mythbackend from a terminal so you can check what is
output?
Also check your setup, in the "cardinput" table you should make sure the
"externalcommand" field is set correctly, if you are using an external STB
this should be set to a script such as "/usr/local/bin/change_channel.csh"
which will call lirc to send an IR signal to the box.
