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.

First and foremost you have to configure the hdhomerun to send IR 
commands to the mythbox with this from the command line:
hdhomerun_config <device id> set /ir/target "<ip address of 
mythbox>:5000 no_clear"
Then save the config in the hdhomerun's flash ram so it will survive a 
power-off:
hdhomerun_config <device id> set /ir/target "<ip address of 
mythbox>:5000 store"
If you want to revert back to not sending IR commands use:
hdhomerun_config <device id> set /ir/target none

Do not enter the angle brackets.  The device id is printed on the bottom 
of the hdhomerun.

Now the hdhomerun will pass the IR along to your mythbox.

irw will now work if lircd is configured properly.  lircd needs to be 
running for irw to work.  If you get nothing with irw, then stop the 
lircd daemon and try running mode2 as follows:
mode2 -H udp -d 5000
mode2 will not work with lircd running.  The switches configure it to 
work with the hdhomerun.
if you get responses from mode2 you can use irrecord to create a custom 
lircd.conf as follows:
irrecord -H udp -d 5000 -n output.file
Rename the output file to lircd.conf and put it in the appropriate place 
for you distro.  Restart lircd or maybe even reboot.
