Not sure if that's an issue with the hdpvr driver or the lirc_zilog driver at this point. I don't actually use my hdpvr for much of anything at the moment, and haven't had time to dig into it.

I have the HD-PVR and I don't use the lirc_zilog - opting instead to
control my STB with Firewire.
The lirc_zilog is only needed if you want to use the IR receiver
portion of the HD-PVR.
Since my HD-PVR is on a dedicated backend unit I don't need IR to work
on that box.
