Does AV Foundation support callbacks now? I thought those were lost when it was implemented.

I was using callbacks to do titling control with streaming audio back when the player still used QT. It worked great until we tried it on a slow internet connection where it fell apart badly. I could never figure out why, since you'd think a callback would report the currentTime regardless of the streaming speed, but it didn't.

We removed the synchronization for that reason. Later I remember hearing that callbacks weren't supported any more on OS X. But it's still there in the dictionary so now I'm not sure where it stands.
