It can interface via the S-video if your computer has that ability, but why do that? It has both firewire and USB. Either can be used to send a digital signal to the pc. Your manual should tell you how.
You will need 'capture' software on the pc. That will take the data sent from the camera and put it in a usable form on the pc. Your camera probably came with software, but, if not, you will need to buy it. Something like Easy Media Creator 7 from Roxio should work.
How can I get the raw video from the MiniDV DV tape on sony DCR-HC40 to my computer?
Can it be done via the S-Video thing?
