Mike I would really like to do this through the backend so that I don't
have to run a daemon on the backend to intercept the commands from each
frontend. Sending the commands through the backend would get them to the
correct STB with a minimum fuss. Doing a query for the tuner and using
a script seemed like a doable workaround till I started to implement it
and found that I would need to contact the backend to get the tuner id,
then setup a daemon on the backend to listen for the command and forward
it to the STB. This is doable but if I could just send the command to
the channel change script through the backend it would be so much simpler
and cleaner. if there is a better way that I am missing then I'm all ears.
