What type of Sony? Disk, harddrive, or mini DVC? You need a cable to go from my Sony Mini DVC to the computer USB port. You hook the camera to the computer and turn the camera on to play back mode. Windows media maker should pop up on the computer and ask you if you want to caputure video. It walks you right thru it. That is if you have a mini DVC (cassette). I have heard the newer disk and hard drive style are not as easy.
