Sony Digital Camera question

man im so frustrated right now i just bought a Sony DCR-HC62E digital camera.
and i test filmed like 20 minutes. it comes with both Casettes , and the Sony Memory stick thing thats in cameras and PSPs. the only cable that came with it was a firewire - usb cable.

my question is. Can i upload video to my pc using the firewire - usb cable ?
(i have a sneeky suspicion i need a firewire - firewire cable or something called an I-Link cable and most pcs dont come with firewire plug ins.)
