Out of curiosity, did you test your book's code against a movie
acquired from iTunes? In my naiveness, I thought the combination of an
iTunes movie on authorized Apple hardware would work out of the box.
(I have not ruled out DRM at this point).

This looks similar to other examples I've seen. There is a noted
difference - the player appears to be part of the Application's
delegate rather than a modally presented view.

Perhaps my expectations are too high - I expect examples from the
vendor should work, without the need for an easter egg hunt. I think
its a reasonable expectation.

OK. I look forward to the day it goes to press (I've got it preordered
via Amazon).
