I have a macbook with built-in isight camera and imovie 09. If I get a Logitech® QuickCam® Vision Pro for Mac® will imovie recognize it as a live camera? The Logitech® QuickCam® Vision Pro for Mac® is usb. imovie does not recognize my sony hdr-xr100 as a live camera because it is usb and not firewire.
