Schlever - thanks, I think.
The forum is full of great ideas.
I've spent a lot of time reading through it , and mining the gems.
Ya go back a couple of years, and there are more great stories about motorizing primestar dishes, and dual band C/Ku LNBs when they first arrived on the scene.
Plus a wealth of earlier ideas on mounting two or more LNBs on dishes.
It's all here.
For DVB PCI cards and USB boxes, see the appropriate forum, here.
There is no real satisfactory solution to blind scanning with a PCI card.
You might want to consider a cheap FTA box for that.
Not sure what's available in CA, but in the USA, IvyStonePlace sells the Traxis 3500
pretty cheap.
Early this summer, I got a Fortec Star Mercury II out of Canada for the same price, but that was
a serious deal!
I don't know how reception is up there, but I got Whitesprings on a 22" dish (see my post earlier in this thread for a picture/link).
That thread also has an extensive discussion of home-made LNB brackets!
So, you might do some research on what you can get on the more readily available smaller dishes.
