This thread is obviously old, but figured I'd post an answer anyway, for others searching...
The Motorola QIP6416 IR driver in the database seems to work, at least for the commands we're using (which most everything except the recording/playback controls). The technician on site says he's not seeing any double/triple commands going out, which is apparently a common issue with drivers for this box.
