IN the HVX main menu area, go to 9. OTHER OPTIONS. IN there you should see 1394-something (don't have the camera with me now). You need to set the camera to 1394 DEVICE.
Connect the camera to the computer via firewire.
Then press the MODE button to get to thumbnail mode. Then press and hold the MODE button again for 3-5 seconds, then a black screen should come up and say 1394 DEVICE DISCONNECT, then soon say 1392 DEVICE CONNECT.
