[mythtv-users] mythsetup question regarding 'master override'

[Robert Kulagowski]

The Master Backend Overide is primarily useful when you have a central 
video storage and slave backends that write files to that store.  
Normally, MythTV expects whichever backend created a file to be the one 
that streams it out to the frontend that requested it.

It used to be that if the slave backend wasn't running you couldn't 
watch the program (even though the master backend still had access to 
the .nuv file).  MBO fixes that.
