log on to http://www.callofduty.com/theater?path=theater , now on your account,you need to find where it says " my links " and then " link my youtube account " and link it , now go on xbox live, start theatre mode, and do the normal stuff, choose your game, place it in file share! . i think you can only render a 30 second video,so try and make it small. wait till it renders the video. then it should in couple of hours or so, be uploaded to youtube! ( automatically i think as you've linked your youtube to callofduty.com, im still to test this out i got sent this tut but in my own words )
