From what I gather from reading the source you get a big queue of screen updates and another queue of audio data and you can tell the kernel to update both at the same time. This way the screen updates and the audio data is kept in sync.

Haven't poked around in the source for a while though so you might want to check to see if what I remember is correct.

There's definately no Hijack support for this though so you can't really use it at the moment without driving the display directly. And doing that would conflict with the player.
