Hi, I have bought unibox HD eco with twin cable/freeview HD DVB-C/T/T2 tuners. So far I have only connected tuner A to a tv aerial via cable and the box has successfully completed an auto scan finding 138 channels but no HD channels. The aerial is HD compatible as I have two identical aerials, one is connected to my samsung tv and receives HD channels with no problem. How can I get the box to receive HD channels on Freeview please?
