So assuming everything attaches to the same dish (?), how do the Vu+, HD51, ET8500 and Formuler F1 and now Octagon SF4008 attach? and do they all pick up the same sats?
There should not be an issue with the FBC tuners configuration, but ......
Also because of the hdmi handshake I am assuming your boxes all go direct to TV's not through an amp?
As you commented I haven't seen any GB driver issues for a loooong while, and over here they get pretty angry if there is an issue, so still looking for some special situation.
Apologies for all the Q's still
