Have two LNBs on exactly the same sat positions with LNBs connected to a multiswitch connected to a SAT>IP server. Here how configured it...
(1) Under Configuration -> DVB Inputs -> Networks you should have two networks added, one for each satellite position / LNB
(2) Under Configuration -> DVB Inputs -> TV Adapters click on each of the (probably 4) tuner entries and make sure that satellite positions is set to (at least) 2 (as you want to address 2 LNBs via Diseqc). Don't forget to "enable" the tuners and don't forget to "save" once you have finalized the changes
(3) You might have to refresh your browser, but then you should see 2 satellite positions under each tuner in the list on the left
(4) Go through the positions, assign the correct network to the individual positions. In my case, I have got the Astra 19.2E network assigned to all the AA positions and Astra 28.E network to all the AB positions. Again, make sure that all positions are "enabled" and all changes are "saved". Easy to forget.
That's it. Rest should work "as usual".
Good luck.
