Oops - Hauppauge 1212 HD-PVR is the device.  Got my part numbers mixed
up<g>.

I'm not too bothered about the remote, since I have a decent
reprogrammable one.  I'll worry about remote control programming once I
get the IR Blaster PC control working within Linux MythTV.

That's good news.

Hmm - the gentoo guys must be a little behind with their releases.  The
latest one in the portage tree is 0.8.7-pre1

Is there a more recent version of this package that I can download from somewhere?

OK.  The lirc zilog kernel module is probably at least part of the
problem.  I may not have that kernel option turned on.  I'll take a look
for that.  Do you know which section of the kernel menuconfig that I
would find it in?  I'm always a bit wary of search and directly editing
the .config file, since that may be a good way to end up with an
incompatible set of kernel config options.

So, if lirc 0.8.7 won't work with the kernel bits, what is the best
solution?  Is downgrading to 0.8.6-r3 an option?

Thanks for the assistance.
