What exactly is it you're trying to do? Incrementing movie time every 
10ms in a loop sounds an awful lot like playing it at 2.5x normal 
speed! If so, why not just set the movie playback rate to that?

I suspect you're trying to play every frame, so some things to think about:
- Setting the movie time doesn't guarantee that that frame is rendered.
- Look at QTCallback
- Try setting hintsPlayingEveryFrame
- Look at MovieController.step()
- Consider using nextTimeStep and visualMediaCharacteristic instead 
of nextTimeMediaSample in your call to getNextInterestingTime so you 
cope with edits etc.
