I'm trying to work out the best arrangement for a PC based receiver for C/Ku band reception.

What I want to do is have a largish dish and a PC receiver that can change between each polarity and band through software control.  The best option would include dish actuator control (though I'm hoping not to need it to get 90% of available channels - or maybe 50%!) and the ability to record and watch separate channels simultanously (bonus!).

Currently my thinking is:
1.8-2.0 metre dish
Invacom TWH-031 LNB (twin output - might need it later, universal)
Hauppauge 3000 (Analog, DVBT & DVBS) TV tuner card.

Which doesn't give me watch and record capability or actuator control as far as I can tell.


I'm a newbie here, but this looks like it will give me C and Ku reception with the option to switch to any polarity.
My questions (unless the above is complete malarky) are:

1. Will I need a Diseqc switch to change between C and Ku bands and can this change the polarity as well?
2. Does anyone know if the Hauppauge 3000 generates the voltage and frequencies to change the LNB reception, (or does it just have Diseqc 1.0)?
3. Even with the TWH-031 LNB, would I still need a two horn cluster (or a one eyed sloth)?

Does any of this remotely resemble an appropriate arrangement?!
