My nice shiny duo2 has arrived complete with 2 dvbs2 twin tuners ie 4 tuners in all. In NZ we only access a single sat and all transponders are accessible through a single lnb. I assume each of the twin tuner cards will loop through to the second tuner on the card but I am guessing there is no way of looping through from one card to the other. If this is so I guess using a splitter will be ok as I only have a single lnb.

Can anyone confirm?
