playStopped use

[Kurt Kaufman]

I know this has been discussed before, but I unfortunately still don't 
"get it":
I need to open up a number of movies one after another, and I'm trying 
to use the playStopped message.

The docs say:
"The playStopped message is sent when the movie or sound reaches its 
end, or when a play stop command executes."

It seems that a handler for playStopped needs to be placed in the script 
of the player itself.  Is there any way I can send "notification" of the 
player's having stopped to a button, or to the card or stack script?

Thanks, Kurt
