Controlled Playback? Help!

[Peter]

Does anyone know if this is possible?
I'm getting no replies!

I have a series of MPEG movies, one per slide. Each movie
loops.
I would like to show a slide with the movie looping
continuously until I click.
Once I have clicked, I need the video to play to its
individual end before moving on to the next slide.

Is this possible?

This is the flow breakdown:

Slide 1
Video A (looping)
Click
Video A completes
Slide 2
Video B (looping)
Click
Video B completes...


Any help would be greatly appreciated!
Thanks.

Peter.
