I've been enjoying March Madness from both my iPhone and iPad via the March Madness Live application. In fact I've enjoyed the app so much I purchased an Apple TV so I could watch games via AirPlay. Unfortunately, when I attempt to send the games to the Apple TV the commercials play but the games do not and instead the Apple TV just displays a spinning icon. Some quick Googling turned up the March Madness Live FAQ which contains this disappointing tidbit:
Is Airplay supported?
No airplay is not supported on this application. The 2012 March Madness Live™ requires a level of content protection that is currently not supported by Airplay.
Additional Googling for AirPlay content protection turns up no immediately useful results. I can speculate what the application developers might be objecting to about AirPlay's security, but I am looking for a definitive answer. Not specific to the thought process of the particular March Madness Live application developers, but in general.
What is it about AirPlay's content protection that would cause an application developer to prevent its use?
There is a somewhat related question concerning why some applications only play audio via AirPlay.
