Sorry for my ignorance and thanks for the clarification Abu.
Going by above, you have told your system that you have a diseqc switch with 4 dishes hooked up to Tuner A.
Not 4 dishes but I THINK 1 and a multi-satellite switchable LNB with 2 coax cables that transport the signal. As I said, it was installed many years ago.
An FBC tuner has two physical inputs if that is what you decide to get.
Does this mean that I need a dual satellite tuner (VU+) or that one of the less expensive boxes (single tuner) would suffice?
So provided you don't get penalties for multiple connections, it would make sense to use both of the Cable tuners.
I only have 1 CI module with the Ziggo card. Doesn't this limit me to 1 connection? Maybe I should have set Tuner C to "Equal to Tuner A"
Thanks again.
