Isn't it an easier solution to just have buttons on the stage that point to frame 1,2,3 etc... and on those frames, you have a stop command in addition to a FLVplayback component with whatever video?

That way, when you click whatever button, that FLV plays?

The only drawback I can see from this solution is it would require some coding to make the video go to the next frame when it finishes playing, but couldn't you just do that with cue points?

But then again, it's early here, and I might just be totally off base.
