If you use the DVi output on the camcorder to a firewire input on a PC you do not need any streaming software installed, however you will require to use Windows XP's media player or any other of the ranges of software about to capture the video from the camcorder into the PC. In other words use a "firewire" coupling between the two, the camcorder using a 4 pin and the other end to suit the PC. (4 or 6 pin)
