How do I capture DV video? (Camera is not found…)?

I have a Samsung SC-D372 MiniDV camera. I bought a firewire cable and used it to connect the camera to my computer. I made sure that the camera was on and in the “Player” mode. I installed the video codec I found on Samsung’s website. The camera did not show up when I tried the “Scanners and Cameras” or “Add New Hardware” on the Control Panel. I tried using two pieces of software, Windows Movie Maker and Vegas, and with both no camera was found. I have tried looking at all the settings I could think of and nothing has worked.
In response to Nu’uanu, I am using Windows Vista (on a Toshiba notebook). I have checked in the Device Manager, and yes, the IEEE1394 bus host controller is listed as working properly. I even tried the “update drivers” option for this device and was told I already had the best drivers. So I don’t think anything is wrong there.
