this has been posted already like 2, 3 months ago. it does not work on any dlc. it only works on some redeemed codes and season passes. And for a side not, not all of the dlc will show up during ingame. You can glitch the license onto your purchase history but sometimes the dlc will not show up during the game. Oh and not all of the online passes are transferable (like the battlefield 3 online pass and saints row 3 online pass). it would probably be best if you tested that dlc glitch out more before you actually just posted it. edit: been wondering this for a while but how do you actually put the video itself onto the post. i put the "[media]" thing in it but it just comes out as a link.
if you just put the link to the youtube video in your post it will automatically show it in your post depending on your browser i belive. i use firefox and if i copy and past a youtube link it automatically codes it to show in my post.
You will just get your xbl account tooken away for stealing dlc so i would suggest doing it at your own risk . If you do if anything you will get ban eta: 1 day and banned permantly so its up to risk you xbl account
