Two Unibrain Fire-I cameras, One Mac Computer and Two Projectors

I am trying to connect two unibrain cameras to one mac computer in order to live recording activities in two locations. And I am using two projectors connect to one computer and each projector will show live recording in one of the two locations respectively.
I am do not sure if it is possible to connect two projectors to one computer? Maybe just like a split screen to display to two monitors? But how to make one computer show two jit.window screens?
Any suggestions?

In my experience daisychaining 2 unibrains is extremely unreliable, besides the firewire bandwidth isn’t high enough for full framerate for both cameras– don’t do it! You will need 2 separate firewire ports– may need an extra firewire card depending on the mac you use; even that scenario may not be particularly reliable.

can’t help you on anything about vid output though (never done it)

Hello, i tried successfully to daisy chain two unibrain at a grab resolution of 320×480. Concerning the two projectors you need a video hardware splitter like matrox dual headto go or triple head to go. Using two videoplanes each with different position you will quite easily have two different videos on the two projectors.
