Hi - sorry to cause confusion!

A hard disc recorder is just a recoder for recording freeview programs for later viewing. It is just an updated video recorder that uses a hard disc, like the one in your computer, to record live TV.

If you do not have anything with a firewire port, you will need an AV cable and a USB video capture device. These will connect to your PC through its USB port.

Just make sure the video capture device you choose is suitable for your computer's version of Windows and also that it comes with some software to help you edit the video.
