ActionScript 3.0 :: Can't Stop A FLV With MyFLV.stop();

I have my Flash piece with three tabs...HOME, VIDEO and PHOTOS. If you go to VIDEO I will have several buttons that you can choose to play different videos. Right now I just have one setup. Once I click the button I jump to a new frame where i have the FLV player ON THE STAGE. The video runs great.....until I go to another frame label like Photos or HOME. The FLV player is NOT on the frame where these others are but yet it still keeps playing.

When I started to try and stop the movie I put "myFLVplayer.stop();" within my button code for the PHOTOS button. This stopped the FLV ONLY if I had went to the VIDEO section and started a movie. If I click the PHOTOS tab before the movie was played I get an error message "TypeError: Error #1009: Cannot access a property or method of a null object reference.at fish_2009_AS3_fla::MainTimeline/photos_clicked()"

Here is my code on Frame 1 of my file with the code in each button...this DOES NOT WORK....why?

ActionScript Code:
stop();
home_btn.addEventListener(MouseEvent.CLICK, home_clicked);
video_btn.addEventListener(MouseEvent.CLICK, video_clicked);

[Code].....

I also tried taking the "video_player.stop();" code and placing it on each of the three frame where I jump to for each section. That did nothing. In the old days when I did this I would have one FLV player on the stage spanning several frames. I wold then jump to specific frame and just load the new FLV into the player. Once I left that frame the movie stopped.
