To the thread in general:
I just checked the box and as expected both DVB-S2 tuners are in use. I can watch terrestrial tv but if I select a satellite station from the EPG I get no free tuner.
My tuner configuration is:
Tuner A: DVB-S2, DiSEqC A/B/C/D, Sats 19.2E Astra, 28.2E Astra2E, 13.0E Eutelsat HotBird, none
Tuner B: DVB-S2, DiSEqC A/B/C/D, Sats 19.2E Astra, 28.2E Astra2E, 13.0E Eutelsat HotBird, none
Tuner C: DVB-T2
Tuner D: DVB-T2
