Need Video out from FCP (MacPro) to an LCD HDTV for Program Output

I am looking for a solution for sending dv and hdtv quality video, ntsc, out of my macpro to an lcd monitor.

Basically, I want to be able to have a real time program output from my fcp timeline while I am editing.

Previously, I have been going firewire out to my camera, then using the camera as an a/d converter, going composite to an external monitor. I would like to bypass having to use the camera in this way.

It would be nice to find a PCI card (or whatever they're called) that has s-video and/or hdmi and/or dvi, so I can plug directly into the lcd. I just want to make sure, though, that I can select this output within fcp.

Any help is greatly appreciated!

Thanks,
