I have a JVC camcorder model GR-D244U. I am using a firewire to connect the device the problem is my Mac Book Pro does not detect the JVC recorder. I have gone to About this Mac> more Info> Firewire but I don't see the device. What could be the problem. please help solve this problem. I have footage of my family members that has passed away and I would like to keep these memories on my computer.
