Similarly to the Playstation 3 you can play regular video files on your XBox 360, here’s how.
Plug in you Hard Drive to a USB port,
Go to My Xbox and scroll right to your Video Library square / button/ tab what ever you call it,
Choose Portable Device with the USB symbol by it,
You should be able to see the folder structure on the hard drive, browse to the video you want to play,
The next screen will show the title of the file, hit Play, you will get a message telling you a media update is required (about 4 meg) you will need to sign into Xbox live, if you haven’t already, do so and hit Play again.
Choose Download Update and the Optional Media Update the Confirm Download,
You’re done, go back and play the file.
