Can't pause the external loaded swf movie

Hello, i’m new with AS3, still migrating from AS2 to AS3

i have a movieclip on timeline, and then i addchild ( a container ) to load
an external swf movie on it. Then i want to have a button so i can pause the loaded swf movie.

And my problem is, i can access to it, i can change the properties like the alpha, but i can just stop or pause it.

Can anyone help me? cause i’m frustrated now :hair:
i’ve been search and testing many script, but i still can make it work
it just a simple task right? i can do it quickly with AS2 :hugegrin:

Thanks 4 ur help :}
