Find out what version DVD drive you have
The xbox 360 to date has 4 different brands of dvd drives:
Here is how you can identify which dvd drive you have (look at the how the dvd try is cut out):

Since BenQ/Philips/LiteOn all have the same shape cut into their dvd tray, you need to take the front panel of your xbox 360 off and look at the color of a wire right under the dvd drive.
STEP 1: To take off your 360 faceplate simply put two fingers inside the USB flap at the bottom of the 360 and pull up
:
STEP 2: Look into the marked area in to see what color the wire is.
YELLOW = LiteOn
WHITE/GRAY = BenQ
