[mythtv-users] Tuner priorities

[Rich West]

This may sound like a basic question, but I've managed to confuse myself 
about this so I figured I would ask.

I just bought an HDHomeRun, set up the channels & etc, but I don't want 
to record on it just yet due to my really poor placement of the POS 
antenna I have.  I have three PVR-150's in the backend already, all with 
a priority of "0".  If I want to have the backend use the HDHomeRun 
tuners as a last resort, do I set the priority of the HDHomeRun tuners 
to something like "10" or to something like "-1"?
