I have been trying to get freeview via Satalite configured on my HTPC

The DVB-S/S2 is a Sundtek SkyTV Ultimate III, because of the linux support. and im using TVheadend for the backend.

I have the 10750 dual throat LNB on a standard Sky dish and have followed the instructions hear on how to add the LNB settings to TVheadend. I've tested the output voltage on the sky decoder and on the DVB-S/S2 both to be 18Volts

dvb_satconf.c

if(!strcmp(id, "Universal")) {
    *f_low    = 10750000;
    *f_hi     = 10750000;
    *f_switch = 10750000;
  }

The frontend status comes back with "No Signal", the mux info is from lyngsat
http://www.lyngsat.com/Optus-D1.html
12456 H DVB-S 22500-3/4
12483 H DVB-S 22500-3/4

adding 000 for tvheadend for kHz

any ideas, it looks like nothing coming back from the LNB but plug it back into sky and all is well...
