[YouTube-API] Re: iOS support for multiple instances of YouTube player

James,

It is an iOS limitation.

On iOS, YouTube videos either play back in an MPMoviePlayerController
instance (if using HTML5 <video> tag) or a custom undocumented
subclass (I think called YTMoviePlayerController) if using the Flash
embed.

Per Apple's docs:

"Note: Although you can create multiple MPMoviePlayerController
objects and present their views in your interface, only one movie
player at a time can play its movie."
