Yep, I understand that now.

That makes a lot of sense, except that the 3 video sources are identical
(apart from the name)?  That's where I have a problem - until a
receiver has been attached to an EIT video source, the video source is
meaningless, right?  After it has something attached, I can reuse the
video source for other receivers on the same satellite.  

I've named my inputs after which LNB they're connected to. 

However, something is still wrong - I can't get to watch any of the
Astra1 channels on my slave backend.  When I pick something on Astra1
from the EPG, the mythtvfrontend just exits.
