Ok. My DMs have triple tuner (DVBS, DVBC, DVBT) . LNB quad ( only 3 can be used). I dont use DVBT at all
My configuration (connection) is :
1. DM800- 1xDVBS + 1xDVBC (Digi) + import DVBC (orange) from H7C
2. Zgemma H7S - 1xDVBS + 1xDVBC (Digi) + import DVBC (orange) from H7C
3. Zgemma H7c - 1xDVBS + 1xDVBC (Digi) + 1xDVBC (orange)
4. DM800 - Import DVBS + DVBC (Digi) + DVBC (orange) from H7C
5. DM800- free. I dont want to use it.
So , regarding no.4: I can put DVBC(Digi) on tuner , Import DVBC (orange) from H7C, and import DVBS from H7c, H7S and DM from N0.1.
BUT to import DVBC (Orange) from H7C to all others receivers, I have to put it as preferred Tuner DVBC.
@abu baniaz: I got your point.
