My Canon ZR800 was working with iMovie. It was completely functional. Now, suddenly, my mac won't recognize the camera. I have tried resetting the date and time on the camera, power cycling everything, rebooting the mac, switching firewire ports, etc. One variable between when it did work and when it didn't, is I acquired an M-Audio FireWire Solo interface. This device continues to work successfully, but it seems that since I started using it (the M-Audio box, using the same firewire port), the camera won't work. To clarify, I am not trying to use both devices at the same time. Another variable: just before my first failed attempt to connect the ZR800, I had connected my iPod. Realizing that the camera may not be able to "coexist" with another firewire device, I disconnected the iPod and tried the camera in either port. Still not working. I know it's not just iMovie, because iChat won't recognize the camera either, which it did before. The camera seems to think it is connected, because it blinks "DV-IN." The cable situation: I had been using a DV to 6 pin cable that came with a friend's M-Audio box. It was working fine. When it stopped working I tried a duplicate of the same cable to no avail. Is this a cable issue? If so, why was it working before? I would deeply appreciate it if someone could help me solve this! I just bought the camera for a specific project and am totally bufuddled as to why it was working fine, and now suddenly isn't recognized. Please help. Peace.
