Would anybody help me? The frontend0 is DVB-T tuner, but this terrestrial norm is to be switch off. So I would like use DVB-T2 tuner which is currently frontend1. I have to use manual intervention since I was not able to teach udev to do it for me (kaffeine works only with frontend0) Any clue please? Thank you Michal
