I've also got the HD-PVR - I would be happy to test the IR blaster
feature on this device if it would be helpful.

I use MythBuntu though - hope that's not an issue.

The hdpvr module on there has the patches to enable IR, as well as the necessary lirc_zilog, so all you should have to do after booting is modprobe lirc_zilog, and it *should* be working.
