At one point I was starting mythjobqueue via a init.d script (from 
memory I think I modified the Fedora script found on the wiki)
I dont recall why I stopped using it, but I found it better (or easier) 
to run the full backend with a Dummy Tuner configured.  (As it 
wasnt/isn't an "approved" configuration for a backend without any tuners 
configured.

Is this the permissions as seen by the MBE or the SBE (mythjobqueue) 
machine.    How are you mounting the directories on the remote machine?
