LOL, yes they are rare, i have to have them made, i think that your issue is software related, load the new v up and run a few tests, remember there are 3 transponders, 1 has TV1, 2 6 and 7 on it, the next has TV3 and 4, the third has Prime , Maori and all other channels, so if you issue is with TV3 audio, it points the finger at that transponder. go to alkris.co.nz for transponder frequencies for your area, hope this helps
