Well, life got in the way and I didn't try this fix until just now..
But it works! I'm going to get my mythtv setup moved into the domU so
I can test it completely, but it seems to work perfectly.

Thank you very, very much. Is removing the conditionals a permanent
solution that can be commited, or is there anything else you'd like me
to test?
