CS4 Several roll over movies played, before continuing on

I want to have several simple movies on the stage, each activated with a roll over. I want the movies to play up to a given point and pause. Only when all the movies have reached the same pause point to I want the roll overs to become active again and allow each movie to continue to the end.

I thought I may split the main timeline into two scenes, where the second scene picks up from the first creating the impression of one continuous scene, as described above. The "pause" could be the end of scene 1 and a GoToAndPlay action at the end of scene 1 could allow the movie to continue, BUT I only want this to happen when all the several simple movies have been individually rolled over and finished playing.

Has anyone got any ideas as I'm afraid I'm rather out of my depth. All suggestions welcomed.
