ah, should have clarified. I want to preview the video on a tv, to make sure it all fits on the screen.

there are a few firewire plugs. 3 are on a card plugged in. the other 2 are on a panel thingy that goes where a card normally would, but are wired straight to the mother board.

I had a similar problem with premiere 6 on the macs at uni. the computer wouldn't recognise the camera. the lecturer gave a list of trouble shooting tips, one of them involved clearing trashes or something. what would that be?
