Full screen mode and (more than one) flvplayback problem in projector

Hi all, I’m new in kirupa forum.

I need help here. I facing a big trouble on as3.0 fullscreen mode.

My presentation have few video, so I need use the frame to breakdown it. when I click my button in main menu to my video on second frame, but the screen just show me the blank black scene. I don’t know what was going on?

this is my first frame script

import flash.display.StageScaleMode;
import flash.display.StageDisplayState;

stage.scaleMode = StageScaleMode.NO_SCALE;
stage.displayState = StageDisplayState.FULL_SCREEN;

stop();

this is my second frame script and have a flv player on the stage

FLVPlayback1.fullScreenTakeOver = false;

stop();

anybody can help me?
