To connect a 4DTV receiver, for both C and Ku, you need 2 cables all the way.When you say a 2 cable solution is that with a disecq switch inline or is it 2 cables all the way to the receiver and no switch at all?
The question is, do you need Ku on the 4DTV?
I'd slave the 4DTV to the FTA receiver. Have the C Band connected to DiSEqC Port 1 and Ku to Port 2.
