At the tuner identification stage you should be able to select a second 
adapter from a drop-down list.  Set it up like the other one.  You may 
find that one of them will work in an active scan, perhaps not both.

My system still has tuner ident problems and I'm reluctant to fiddle 
with that part of the setup without good reason, but this may only 
affect Fedora-based boxes.  If you can't identify another tuner see

During recording you should get a passive scan of that mux, so you could 
try scheduling recordings just to get the data; but try active on just 
one tuner first.
