My remote is a Logitech Harmony One, and in the Logitech software I set the device type to "MythTV". My IR receiver is an HDHomeRun TV tuner, and it's fowarding the IR signals to UDP port 5000 on the MythTV server. I know that the HDHomeRun is working properly, because both tcpdump and mode2 show that every key press is received.
I finally got good mode2 output after upgrading to lirc 0.8.6, you can see it at http://paste.ubuntu.com/273633/.
Thanks, and have a great weekend!
