If you want to use the USB cable to connect the Camera to the Computer to transfer the video to the Computer then:
(Applicable for Vista Operating System Only.)
This Camcorderdoes not support USB streaming with the VISTA Operating System. Use ani.LINK cable to transfer the video to the Computer. The i.LINK port isalso called IEEE 1394 or Firewire port. (An i.LINK is a black D shapedconnector with 4 or 6 pins. The type of cable to be used will depend onthe i.LINK port of your Computer. The Sony Camcorder will have the 4 pini.LINK cable and if the computer has the 6 pin i.LINK port, then you mayhave to use the 4 pin to 6 pin i.LINK Cable).
You can use any video capturing software like Windows Movie Maker to transfer the video from the Computer.
