Missed your post the first time through, a title of "Help!" really wont do much to help you as no one knows what you are on about and will prolly not waste their time trying to figure it out. The more descriptive the title the more likely you are to receive help.
So what kind of machine are you referring to? Something that is standalone that you simply plug the camera in to? Or that is connected to the PC? If your camera is too old to plug in via USB then you will probably need a Video Capture Card or device such as THIS.
