Not sure why, but as of late all of a sudden commands will not work with my HTPC from the Harmony One. The HTPC uses the Imon software (Thermaltake case). I have to reprogram the remote in order for it to work, but the last time I tried even after reprogramming it still didn't work.
The programming for the TV still works fine (you can turn volume up and down, shut on and off), it is just the WMC commands.
I might just bypass the Imon IR receiver all together and just use the Logitech IR extender that came free with the remote, but I'm assuming I need some IR USB receiver in order to use that extender?
