Chipp,

1) I'm not aware of any callbacks that Revolution exposes.

2) For my projects I just use send in time to monitor playback.

3) When you mention the SMIL extensions are you referring to the QT  
ones mentioned at the url below?

If so and you already tried <smil qt:time-slider="true"/> then I don't  
know what else to try. If you have tried <smil qt:time-slider="true"/>  
then see if it works for you.
