I have one of these that I used as a receiver for MythTV for a short while. I found that I had to be very very careful when learning the keyboard IR to only use one short keypress, that way the Harmony learned the single code and not a bunch of them repeated. Took a few attempts but it worked pretty well, no changes to MythTV or the Harmony.
