Update. Well, it was a polarity problem. I just did'nt fully understand how polarity was being set. Since its "set" (in my case) by the 4dtv by changing channels, the FTA receiver can only show channels of whatever polarity the 4dtv is on. Same goes for scanning in the FTA channels. Anyway, If I don't get a picture on the FTA, all I have to do is change channels on the 4dtv (this changes polarity for the FTA). It works ...
