Videos on several slides in different scenes start at the time
I have a problem with a video-based e-learning created with AS2.
Sometimes two videos on different slides in different scenes start at the same time and I can not understand anything, because the soundtrack of both videos running side by side. Of course I only see one video (that, that is included in the slide I just launched) but I hear the sound of another video in addition.
The videos on both slides start automatically when the timeline starts. And I have the feeling that this problem appears more often, if the corresponding slides are in different scenes.
Do you know that problem? Do you know how to avoid this?
