I'd stick to just what's on the HDPVR wiki page, most of the stuff on
other pages is for other devices (mostly serial).

I think I covered that in reply to an earlier thread. Create an
executable shell script at /etc/sysconfig/modules/lirc.modules, and
put in it:

#!/bin/sh
/sbin/modprobe lirc_zilog

No, you're fine.

Don't do any of that.

Don't do any of that either.

You're making it way harder than it really is. :)

Just set the module to load on startup using the lirc.modules trick,
grab the channel-change script from Mark's Braindump, modify it for
your specific codeset, configure MythTV to use it for changing
channels for your hdpvr recording devce. Done (since you've already
got the lircd.conf in place).

Now, you *do* know that there have been reports of varying degrees of
instability using the IR part in the HD PVR, right? It has a nasty
habit of leading to the HD PVR itself deadlocking (doesn't take out
the computer its attached to, but the HD PVR is useless until its
fully reset).
