My setup will be a bit different than yours since I'm running a OS X backend, but a lot should be the same.  First, I use the following parameters to have lircd listen for the HDHomerun:

lircd --driver=udp --device=5000

Next, you have to a configuration file that matches the remote codes that you're going to have the Harmony send.  I chose the remote for an older model Panasonic DVD since there was a complete-looking config file on lirc.org and the buttons available seemed to match well with Myth functions (ie "Menu", "Info", etc).  Put the lirc.conf file in the right place (likely /etc) and configure the Harmony to send those codes.  I *don't* have that DVD player--it is just a convenient set of codes that won't conflict with the devices I do have.

I seem to remember that irw can't receive udp-based activity.  Maybe try ircat?

Finally, you need a lircrc config file to map button presses to Myth commands.  See:


Hope this helps,
