I have Zgemma h2h, I've been trying to program a zgemma hs for my mum so I disconnected my cables. When I plugged them back into h2h I've lost my cable channels. My SNR is sitting at 117% and AGC is about 7% and only picking up 4 HD channels when I do a search. No other cables channels found. Yet when I have my VM box in I still have my normal channels through that? Any suggestions?
