"How do you upload footage from Sony HandyCam to iMovie?
I'm trying to upload videos from my Sony HandyCam to my Mac OS X iMovie. When I open the iMovie application, I wait to see if it recognizes the camera, but no luck so far. I've been reading some forums, and it's been rumored that the Sony HandyCam isn't supported by the Mac OS X system. Please let me know your suggestions and tips. It's much appreciated. Thanks."
