Some of you know what you're doing with configuring WinTV7 - I need your help please, I'm still learning.

I've just had installed by a Sky sub-contractor a feed from a MySky HD box to two bedrooms where I've set up a very nice mobile media centre built around 19" Bravia - various functions but the important one here is provision of Sky on the feed. I liked it so much I've had an identical box installed in my study where I want to take the feed to the Hauppauge HVR3000 hybrid card installed in my desktop (NVIDIA GeForce 9800 GT, AMD Athlon 7750, 4Gb RAM; running Windows 7 build 7000 - I'm downloading the Win7 RC as I write this but I want to figure out this issue before I install the RC).

Hve been messing around with WinYV7, WMC and Media Portal but I want to perservere with WinTV7. I have no problem configuring Freeview using DVB-T and reception is excellent (Karori, Wellington). But I want to set it up for the satellite feed including Sky (using, I presume, DVB-S). And I can't even get to first base with configuring WinTV7.

The first window for Digital DVB-S setup has a series of options I don't understand - Single LNB; 22KHz A/B Switch; DiSEqC1 x A/B/C/D - which of these should I choose? but, more particularly, a drop-down list for the satellite - which doesn't include the OPTUS D1 NZ-13L satellite currently used by Sky.The D1 (160 OE) is listed, and an entry for OPTUS D3 (plus, of course, many others) but the D1 NZ-13L.

Any of you able to help me get past this first set of options?

Edit: should add that I've already tried setting to Optus D1 (160 OE) and trying the other settigs in turn, but scan doesn't produce any results...
