I am working on a web site with multiple Quick Time movies, each on their 
own layer, with autoplay set to false. There are links to pop up these 
layers... and only one should play and be visible at a time. I want to 
assure that when a different movie is selected that all other movies and 
layers are stoped and their layer is hidden before popping up the other 
layer.

movieName.Stop()

causes an error if the movie is not currently playing. Any words of wisdom 
on this subject would be greatly appreciated.
