I heard recently
(http://www.mythtv.org/pipermail/mythtv-users/2011-January/307965.html)
that you're supposed to add the HDHR to myth using it's device ID, not
via it's ip address.  I was having an issue with recordings being cut
short prematurely, this fix seems to have worked for me.

The CLI is everywhere. It's all around us, even in this very room. You
can see it when you look out your window or when you turn on your
television. You can feel it when you go to work, when you go to work,
when you pay your taxes. The GUI is the world that has been pulled
over your eyes to blind you from the truth.
