Sony DCR-HC48 Can't Transfer Video to Computer

With Windows, the USB is for transferring data from the memory card and i.link is for transferring the contents of the tape.

If you have a desktop computer , you can easily add an i.link card.

If you have a laptop computer, you can easily add a Cardbus with i.link.

Here are examples:

Sony calls it i.link, Apple calls it Firewire, some call it IEEE 1394.
But they are all the same thing.

I borrowed a friend's Sony DCR-HC48 camcorder to record a small event for a group of youths. However, when I later on decided to capture the video to my PC via the IEEE1394 port for editing, I discovered that the camcorder has no such a port. It only has an A/V port for analog capture next to the DC-IN jack located at the back of the unit. How is that possible? Or is it located at some obscure place? I can't find it anywhere on the camcorder! Anyone with any ideas? Thanks.
