Hi. My zgemma on iPab 1.3.1 running on cable only, I had to have sat enabled or you would get no channels to work. I am now running 1.3.6 and had the same problem. Scan says over 400 channels but none work. If I manually scan each transponder frequency every thing works ok. I just can't get it to work automatically. Sadly the channels disappear overnight so can only be recovered doing manual scan. The settings now don't like sat enabled with no input. My appreciation for any suggestions.
