(Applicable for Vista Operating System Only.)This Camcorder does not support USB streaming with the VISTA Operating System. Use an i.LINK cable to transfer the video to the Computer. The i.LINK port is also called IEEE 1394 or Firewire port.
(An i.LINK is a black D shaped connector with 4 or 6 pins. The type ofcable to be used will depend on the i.LINK port of your Computer. TheSony Camcorder will have the 4 pin i.LINK cable and if the computer hasthe 6 pin i.LINK port, then you may have to use the 4 pin to 6 pini.LINK Cable).
