John, this may help - this is what I had to do to tune in the decoder at our work. It was a non-approved decoder so it did not automatically update. If you google Lyngstat+Optus D1 you will get all the settings for NZ satellite. The decoder I tuned had totally lost all its settings, it did not even have Optus D1 on its list of satellite so I had to do a "manual setting" to other satellite. I then had to set the search parameters for each frequency (and tell the decoder to only search for unlocked/unscrambled channels). Polarity is set to horizontal. Once each frequency was input I had to do a search on each frequency. Also set SID to 22500
Frequency 12456 search gets channels 1, 2, 3, 3+1, 4 cue, shine and choice
Frequency 12483 search gets channels Maori, 1+1, 2+1
Frequency 12671 search gets channel Trackside
Frequency 12707 search gets channel Prime
It may be that somewhere on your system on your current system you can see your existing channels, hopefully they match the information I have above. Then you just need to work out how to manually search for the 12707 frequency. Good luck.
