Instructions
Pick up the controller that is controlling the Xbox 360 Elite.
Press the "X" button if there are no lights on at the top of the controller. If there is a light on, skip this step. The light will blink a couple of times while the controller connects to the Xbox 360 Elite.
Press the "X" button. On the menu that appears on screen, select the words "Open disc tray." Press the "A" button to select this option.
Take out the DVD in the disc tray and replace it with the DVD you want to watch next.
Give the disc tray a light push inward and the console will close the disc tray and load your new DVD.
