I upgraded my MythTV box from Feisty to Gutsy this morning. Everything seems in working order - except my IR Blaster.

The first thing I did on upgrade was to follow the guides to recompile the lirc-modules-source to get the transmitter working again. When I attempt a channel change, the transmitter's red LED blinks successfully, but it does not change the channel on the cable box.

I've purged, then reinstalled lirc, I've recompiled the lirc-modules-source over and over again, I really don't know where to go from here. Any help is greatly appreciated.

I've even reverted to the IR Blaster as my only lirc device, and it still won't successfully change channels. It doesn't give me any error messages when using irsend.
