I recently purchased an imac 24" with intent of video editting some of my mini dv's. My camcorder is a jvc gr-d375u equip with a 4 pin firewire out. I did some minor reasearch and purchased a 9 pin to 4 pin cable from the apple store. Unfortunately, my mac doesn't see it. I've restarted, etc. checked out importing in imovie and iphoto but it just don't reconize the connection. Any idea's or am I sending the cable back?
