Controlling playback

I would like to know if there is a way to use a controller playback (fast forward and rewind) to control numerous swfs.

For example:

Main.fla holds the controller
Main.fla calls up several demos that play linearly.

there are six demos. the demo.fla is set up with movie clips on the main timeline(to control total frame #) – otherwise the audio alone would make a demo over 16,000 frames (the macromedia flash mx 2004 limit)

now is there a way to have the main.fla fastforward and rewind these demos so that at the end of one, it jumps to the other and and the beginning of one you can rewind to the end of the previous? So that it rewinds and fastforwards inside the movie clips not the main timelines of the demos?

please help!
thanks
