Ive just come to my camera to get some clips off using a firewire cable but for some reason the footage wont transfer onto the computer, instead all i get is a blank screen (black) and the computer says no frames where transfered or something. At first i thought it maybe the tape but ive tried another one and i had the same problem so it must be either the camera or the settings on the computer, does anyone have any ideas or better yet know what could be causing this?
