Ignore that bit about NICAM/OSCAM I got you mixed up. You only have one dish. A Viark is best with a motorised dish. If you stay on 28e with an E2 box you only get all the FTA channels. IPTV is best with a dedicated box but it will still work well with the UNO.
When you change the LNB to a quad you will have 4 outputs but as you have only 2 cables then you can connect 2 boxes, the Viark is a single tuner and with an E2 box with 2 tuners you can disable one and use it as a single. The idea of the 2 tuners is for recording one and watch another.
