Thanks for your help.
The 'inf' file (….\x9320_Windows_Dirver\x64\x64inf\cydtv.inf) does not include the x9320 card among the Geniatech devices listed.
The only DVB-S/S2 devices that are listed are the SU2000, 3000 & 8000.
The four USB Stick devices installed by the card (which appears to act as a USB Hub) have the following hardware Ids - USB\VID_1F4D&PID_3300, 3301, 3302 & 3303
Since I'm going to use this PC as a HTPC I don't need Windows and will try to get Linux working instead.
I don't think I'll ever buy from GeniaTech again after this experience.
