I need to capture PS3 menus etc for a review. But the only way to do it without pointing the camera at the screen is to feed the output of the PS3 into my camcorder. The only inputs on the camcorder are iLink Firewire. (I can't capture to PC as I don't have a capture card). So I need to convert the HDMI output of the PS3 to firewire input of the camcorder. Is there such a cable? Will this work?
