lirc should be used to inject input events and probably nothing else.
There are three different lirc daemon flavors, each one missing key
features. If you need to merge multiple sources, you have to do a
confusing dance with tcp sockets, master servers, etc. Unfortunately,
the event driver interface is one thing in lirc that apparently
doesn't work at all.

I made it work instead with gizmod talking to the mythtv telnet
control connection, see script.

Gizmod does have a problem with its compile prefix, see
https://bugs.launchpad.net/ubuntu/+source/gizmod/+bug/645058

So, the complete hack under ubuntu 10.04...

* add uinput to /etc/modules
* tell myth to use the pulse device
* add to /etc/pulse/default.pa: load-module module-alsa-sink device=plug:dmix
* click the headset button to connect it
* use pavucontrol to move the myth stream over to the headset
* install the script below in ~/.gizmod/modules.d/001-AVRCP-MythTV.py
* sudo ln -s /etc /usr/etc
* sudo gizmod
