BTW. I think it may be something to do with MythBackend starting before 
the HDHR tuner is up and running. Restarting the backend does not fix 
this issue.

There was a power failure after my fix above (welcome thunderstorm after 
the heat wave here in MI) and both my MythBackend box and the HDHR were  
rebooted.  The backend could not tune into the card again. I had to 
reboot to get that working.
