Can I get a twin lnb to work with my system

booji

After recently intalling a new system (with old dish) I had intermittent motor problems, after much tracing I found the PC card was shutting down the power to the motor when the motor was moving from certain positions along the arc (even with the dish not attached).
I have solved the problem (hopefully) by swapping my new 4 port titanium (230mA current) with my old cambridge LNB (80mA).

I am a bit dissapointed as I wanted eventually run 2 PC sat Cards in an HTPC.

Has anyone managed to run a quad or 2 port LNB off a motorised system and PC card? If anyone has please let me know.
