No Camera Attached - but it is

[TheSpaceBetween]

So I'm trying to upload some video into my archaeic iMovie 4.0. However, with the camera attached and in Playback mode, iMovie still says No Camera Attached.

edit: I tried ALL of the suggestions here:

The camera IS a Sony Handycam. None of the Sony-Specific suggestions work.

edit2: So I remember what I did last time this happened. I used Final Cut Express. I'm trying it now, but cannot find the device through there either...

 

[Queso]

If you look in the Apple System Profiler (More Info.. button on the About This Mac window), does the camera show as a connected FireWire device when it's plugged in and powered on?
