Ok just got a Canon Optura 600 and I can't seem to get iChat to work with it via firewire. I put the cam in network mode, start iChat. iChat see's the camera, but all I get is a black screen. A lot of times I get the message that the camera isn't available because another program is using the camera. I hope my cable is good, it's a firewire to DV cable I got with a powermac years ago. I have used the cable and it does pull files off the camera in iPhoto. I also tried using the camera in Photobooth and it sees the camera, but again I get a black screen. Since this is a new cam, I don't have a Tape, could it be because I have no tape?
