I need the logs from the non-working separate frontend/backend systems 
to tell you why that's not working.

There are no "slave" frontends--only slave backends.  Therefore, the 
frontend can only be a slave if it is a combined frontend/backend.  If 
it is not a combined frontend/backend (i.e. it does not have capture 
cards), you do not configure the video sources on the frontend.  
However, LiveTV can fail if the video sources are improperly configured 
on the backend.

But, we're just guessing here because we have absolutely no information 
on which to base our conclusions...
