Checking to see if the FLV Playback component is playing

programming flash
1

I have a FLV Playback component set up on my stage with a video chooser under it. I need to see if the player is playing because if I click the same video that already playing my play button comes up and the video starts to play again. I am including the code that I have on the chooser button:

thumb2.onPress = function () {
    vidPlayer.removeEventListener("complete", shareLinks);
    videoToPlay = box2;
    vidPlayer.seek(0);
    vidPlayer.stop();
    checkAd();
    if(textAdVisible == true && textAdType[videoToPlay] == "full"){
        closeAdFull();
    }else if(textAdVisible == true && textAdType[videoToPlay] == "half"){
        closeAdHalf();
    }
}

It seems that as long as I choose a different different video than what is playing it works fine.

thanks in advanced for any help
