Since the Sony Vaio laptop does not have a firewire port, I don't see how to connect it to my Sony HVR-Z1U video camera, which only has a firewire port. I do have a cable wire that has firewire connector at one end and a USB connector at the other, but it doesn't connect the two. The Vaio doesn't recognize the camera and the tech guy at the camera store says it won't because you can't really transfer video streams via USB. So how can it be done? How can I connect these two devices?
