if this is the sat then what you would need to do is to add muxes manually.
Hopefully you'll only need to add one and it should be able to discover the rest off that one.
just follow the info bellow.
add the sat but leave predefined empty.
then for each mux (hopefully 1 and the rest will appear if not compare lists and add missing ones)
go to muxes tab and choose add mux.
Select Sat from drop down box.
Make sure to fill in the folowing fields
"frequency":xxxx000 take from info above ignore any decimals etc and add 3 zeros to it
"symbol_rate": xxxx000 take from info above ignore any decimals etc and add 3 zeros to it
"fec"
"polarisation"
"modulation"
"delivery_system"
the other boxes can be left alone
