hi smash, are you on a mac or pc? what is the model # of the camera? sounds like from the age of the camera, you will have to come out of the camera thru video out (yellow RCA female) into a video card, or external peripheral box. so yes you have to buy stuff. some of the cheaper boxes make nasty copies but then I haven't used one in a while. I go into a mac (which has no video in) with a JVC GRD230U DV camera (firewire out), fairly cheap but great results, runs good and has analog inputs so I can use it as a "video in" into the mac via firewire. works like a champ. If you had one of those cameras, and if you're on a mac, you could go video out of your old camera into and thru the new camera and then via firewire into the mac. I've done it works great. To me a camera makes more sense than a box as a video input device, and you get a dv camera as well. It's a bit different on a PC.
