It wont be able to stream audio/video most likely unless it is a webcam. But when you can do is record the video/audio clip on the camera and then connect the cam to your computer (via USB , IEEE1394, etc...) then save the clip to your hard drive.
Yeah right on tatertot. My DC is the same. I can only do 2 minute clips....But you can piece them together with easy video joiner if you want. Kind of a pain, doing multiple clips. But joining them is easy.
