[mythtvnz] OT connecting to sat dishes to one receiver

[Nick Rout]

Subject says it all I suppose. A friend has two dishes, separately
wired back to the lounge. One is a sky dish (but they have so sky box
at present). The other points at some other satellite - Optus B3 IIRC,
and is attached tro a generic DVB-S box.

I figure if they can connect the Sky dish to the generic STB they will
be able to watch freeview too. I also assume its not as simple as a
splitter to bring both aerial feeds into the one STB input.

So how do I do it? Is this a DiSEq thing? If so where do I get one and
how much are they?
