Simple stop FLV video script on Enter_frame

I have a FLV video that I need to stop when my flash video reaches a certain frame.
I named my video “SMB3video”
Using AS3.

I don’t want something super advanced, just keep it as simple as possible.

I tried to create a script which gave me no errors until it reached the frame for the timeline.

this.addEventListener(Event.ENTER_FRAME,ent_frame);  function ent_frame() {     SMB3video.stop(); }
