Frontend and backend are on different machines so that counts out your 
second option.  You are correct in the first instance that the backend 
and frontend are not running as the same user.  Backend is running as 
mythtv user while frontend is running as another.  This user belongs to 
the mythtv group and so should have read access to the recordings folder 
(new recordings seem to have read access for all anyway). 

What I do have is symlinks.  The default location for the recordings in 
myth is /var/lib/mythtv/recordings but I have that location symlinked to 
another location.  The ownership and group are both set to mythtv user 
with read/write/execute permissions for owner and group.  I didn't think 
that there was any problem with this set up as the backend is currently 
recording programs to this location happily and I can watch any existing 
recording from the same location.

I don't know maybe there is some subtle difference in the way the live 
tv recordings are handled...

Here is another output.  This time it went to the first channel under 
livetv but died on channel change.
