To Record Directly to the Hard Drive with a Firewire Camera:
1. Turn on your camera and make sure it is in Camera mode as if you were recording to a tape.
2. Be sure your camera is firmly connected to the computer using firewire (USB will not work)
3. Than in iMovie move the slider to the camera side.
4. You should now see live video from your camera on your screen. If you hear a loud noise its because your cameras built in mic is to close to the speakers, try muting the computer or move the camera away from the computer.
5. Click record in iMovie and your set.
Note: If the camera is in "camera" mode and is left on and if it is not physically recording to any tape, than it may auto shut off. Use an old tape and record on to it. When you are done with that tape, rewind and record again since you are not really going to be using the tape.
