Why is this confusing?  You have to define the cards on the machine that 
can actually query for the video devices.  It spells it out in the docs: 
The configuration of a non-master backed is the same as the master 
except you skip over the Video sources section.  I'm not sure why the 
Video sources section has to be skipped because the video sources table 
in the DB has no host specific options in it so they should be universal 
to whatever backend is doing it, but it maybe simply related to a desire 
to keep listing related functions relegated to the master backend only 
because it runs mythfilldatabse. 

Perhaps it should be considered to grey out or disable Video sources on 
non-master backend systems to prevent confusion.
