I'm not sure to understand your question. Could you use an example?
miniMAD synchronization basically works using the following two rules:
Movie synchronization happens on every miniMADs playing a movie with the exact same frame count and
framerate, even though their file names are different.
Every media-related action made on any miniMAD happens instantly and automatically to every miniMADs: media change*, pause, restart,playback mode, audio mode, image display-time.
* media change works properly if every miniMADs contain a file with the same name, even though its content is different
