Is your camcorder attached to your computer via USB, is it set to VTR and have you established a connection between your camcorder and your computer? (If so, you'll be able to see the camcorder in Windows Explorer.)
Once you've done that, did you use Add files/From Cameras and Devices to launch the Video Importer to locate your files?
Please share any details you can about your process.
