i will gift my original animations at http://3dfiction.com
thanks in advance. here is the my code


var loader_mcl = null;
var target_mcl = null;
var preload_anim_visible:Boolean = false;

// Loader callbacks ----------------------------------------
function onLoadStart(target){
    trace("load start");
    target_mcl = target;
    attachMovie("preloader anim", "preloader_mc", 500, {_x:0, _y:0});
    preload_anim_visible = true;
}

function onLoadProgress(target:MovieClip, bytes_loaded:Number, bytes_total:Number){
    trace("load progress "+bytes_loaded+"/"+bytes_total);
    target.stop();
    target._visible = false;
    preloader_mc.value = bytes_loaded/bytes_total;
}

function onLoadComplete(target){
    trace("load completed");    
    target._x = 0; 
    target._y = 0;
    target.play();
    target._visible = true;
    preloader_mc.removeMovieClip();
    preload_anim_visible = false;    
}

function onLoadError (target, errorCode, httpStatus) {
    trace("load error: "+errorCode+","+String(httpStatus))
    stopMovie();    
}

// Loader helpers ------------------------------------------
function startPreload(url){
    // create a new loader
    stopPreload(); // remove a previous one in case it's still around
    loader_mcl = new MovieClipLoader();
    loader_mcl.addListener(this);        
    loader_mcl.loadClip(url, container_mc);
}

function stopPreload() {
    // detach the loader to free it
    if (loader_mcl != null) {
        loader_mcl.removeListener(this);
        if (target_mcl != null) loader_mcl.unloadClip(target_mcl);
    }
    if (preload_anim_visible) {        
        preloader_mc.removeMovieClip();
        preload_anim_visible = false;    
    }
    target_mcl = null;
}

// Button events -------------------------------------------
function startMovie() {
    movie1_btn._visible = false;
    stop_btn._visible = true;    
    startPreload("http://3dfiction.com/swf/fr22x.flv")
    // work with "http://3dfiction.com/swf/fr22x.swf" but not with "http://3dfiction.com/swf/fr22x.flv"
}

function stopMovie() {
    movie1_btn._visible = true;
    stop_btn._visible   = false;    
    stopPreload();
}

movie1_btn.onPress = startMovie;
stop_btn.onPress = stopMovie;

// Initialization ------------------------------------------
startMovie();  // this works good for initialization
