I go into installation and SAT/TP Edit, select the satellite and go Add TP. A box comes up with fields for the entry of Frequency, Symbol Rate, and Polarization. But it only lets me change the polarization and I can't set the frequency or symbol rate which are both at zero.
The same problem occured when I tried to add a new satellite - I added the satellite, then it said I had to add a TP but it wouldn't let me set up the TP. That's why I just edited the Optus B1 in the first place. My decoder is a Topfield TF4000Fi.
