You will need to purchase an X-port or a Max Drive. You can get these from play.com or amazon.co.uk
I'd recommend the Max Drive over the X-port myself - less hassle.
You can then transfer the replay files from your memory card onto your computer.
If you want to make videos of the goals, you will need a tv card. If you send the replay files to myself or stevieboy then we can capture the goals for you.
