Yea there are some secrets of QT... we have to beat up Apple engineers to
get them (sorry Kevin =)

I am considering using your method, which obviously works much better than
mine, but I'm just not sure which is the better way to go... Directly or via
VorbisFile. If I manage to cleanly implement VF, future updates won't be as
difficult as the Vorbis libs evolve.

Scary thought!!

Bummer..............

This one has me confused, but it might be specific to my iBook. I have one
of the betas of 10.1, but unfortunately Apple broke QT component support in
this beta. I can't test it this way.
