Flex 4 spark Video Player how to play from currentTime

Question

there are 4 Videosource so that the user can switch between it with the same progress of Video.

How can I implement this? The funktion seek(time:duration):void dosn't really work. :-(

my Code that I use:

<?xml version="1.0" encoding="utf-8"?>

<fx:Script>
    <![CDATA[
        import mx.events.VideoEvent;

        import org.osmf.media.MediaPlayer;
        import org.osmf.video.CuePoint;

        protected function button1_clickHandler(event:MouseEvent):void
        {
            var playing:Boolean=VideoPlr.playing;
            var time:Number = VideoPlr.currentTime;
            VideoPlr.source = "http://helpexamples.com/flash/video/water.flv";
            // dosn't work this.VideoPlr.seek(VideoPlr.duration * time / 100);
            if(playing) VideoPlr.play();
        }


        protected function button2_clickHandler(event:MouseEvent):void
        {
            var playing:Boolean=VideoPlr.playing;
            var time:Number = VideoPlr.currentTime;
            VideoPlr.source = "http://helpexamples.com/flash/video/clouds.flv";
            // dosn't work this.VideoPlr.seek(VideoPlr.duration * time / 100);

            if(playing) VideoPlr.play();
        }


        protected function button3_clickHandler(event:MouseEvent):void
        {
            var playing:Boolean=VideoPlr.playing;
            var time:Number = VideoPlr.currentTime;
            VideoPlr.source = "http://helpexamples.com/flash/video/cuepoints.flv";
            // dosn't work this.VideoPlr.seek(VideoPlr.duration * time / 100);
            if(playing) VideoPlr.play();
        }


        protected function button4_clickHandler(event:MouseEvent):void
        {
            var playing:Boolean=VideoPlr.playing;
            var time:Number = VideoPlr.currentTime;
            //VideoPlr.source = "http://helpexamples.com/flash/video/cuepoints.flv";
            if(playing) VideoPlr.play();
        }

Here is my solution:

There are four files that can be switched in your deisgne. Each switch make jump to time in a new sourcefile.

<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" 
               xmlns:s="library://ns.adobe.com/flex/spark" 
               xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600"
               creationComplete="createHandler();">

        <s:BasicLayout/>
    </s:layout>

thanks for your restraint.
