Hi Rolf
Thanks again for your reply. How the heck did you find that? I've searched and searched for anything related to Omnisat without luck. So this person has managed to use a Hauppauge card (which Hauppauge say you can't) with an Omnisat (which specify a max dish size of 80cm) and a dish of 1.1m - hummmm.
The Omnisat positioner has a 24v input that I have never used, I think I'll provide power to the 24v input remove the receiver and see if the dish moves (powered only by the 24v input). If this works then I'll go for a Nexus - s (as this seems to be the most recomended) and try it. If it works then great, if not then it gets sent back as faulty and I'll just use the old pacer kit to drive the motor then switch the coax back to the nexus.
