I run an HD-PVR on my mythtv system and I have no need for irsend, nor does
the HD-PVR get involved with channel changes.  In my case, I have a STB
fronting the HD-PVR, and I use a firewire cable from myth to the STB to
change channels.  I use a script derived from 6200ch or something similar.
The PVR doesn't get involved in this activity and only captures whatever
the STB sends it.

Is your setup different?
