is there a way of getting the videos on my 360 hard drive on to my computer

You have to get a USB connection cord. (A cord with one side as a USB plug, and the other as a phone jack plug.) Connect the phone jack side in the back of the Xbox, and the USB in the computer. Or it's all just a phone jack. It's something like that. Go to Best Buy or Circuit City and ask your question, they might know.
