I currently own a Nikon D200 and am looking for a cable that will allow me to preview images on my laptop vice the camera's LCD screen. The camera comes with an RCA cable which you can plug into the camera and then plug into any RCA port on a TV. Unfortunately I would like to plug this cable into my laptop but there is no RCA jack. I only have USB, S-video & firewire ports. I do not want to buy a small TV for my studio but would rather just use the laptop I already have. The couple of places I contacted could not help me. Anyone have any suggestions?
