Hmm I guess you need to setup 2 video sources. Because with your setup, 
IIUC, you are telling the backend that both tuners "share the same 
source" basically meaning that they can only tune to the same mux. So 
all you can do with your setup is watch 2 (or more actually) channels on 
the same mux.
You can also set virtual tuners: each "real tuners" can record several 
channels on the same mux. So with 2 tuners you can end up recording alot 
of shows ;-) But you need as many video sources as tuners.
Please someone correct me if I'm wrong ;-)
A+
