I found out you may have to disable Mac filtering on your router to get AirPlay to work. Thats what I had to do for my airport express, apples website recommends it. This really sucks for me because I live in an apartment and as soon as I do that someone try's to crack my network, so I can't use AirPlay.
----------
With the Mac filtering is turned off I can AirPlay games from my iPad, when it's turned on it fails.
