Ok here is a photo guide and short tutorial
The pop-down DVD window is held in place by an aluminum shroud which is in turn held in place by four tabs. If you look at the first photo I have labeled the tabs 1-4. All of the tabs must be popped out of place if you want to remove the DVD window. The bottom tabs (1,3) have to be pushed in farther than the top tabs (2,4). I found it is better to loose one side and then the other. Once all four tabs are out you can slide the entire assembly out. Once out you can easily remove the aluminum shroud. Reinstalling the DVD window is as simple as following a reverse of the above listed proceedure.
