NetStream.resume() has no effect

Hi everyone,

I'm developing a videos slideshow in AS3. Here my Video.as class that handles connection&stream of each player :

package com.dm.player
{
    import flash.display.Sprite;
    import flash.media.SoundTransform;
    import flash.net.NetConnection;
    import flash.net.NetStream;
    import flash.events.Event;
    import flash.events.NetStatusEvent;
    import flash.events.SecurityErrorEvent;
    public class Video extends Sprite
    {
        private var config : Object;
        private var connection : NetConnection;
        private var stream : NetStream;
        private var video : flash.media.Video;
        private var addedToStage : Boolean = false;
        public function Video(config : Object)
        {
            this.config = config;
            this.addEventListener(Event.ADDED_TO_STAGE, this.onAddedToStage);
        }
        private function onAddedToStage(event : Event) : void
        {
            if (this.addedToStage)
            {
                return;
            }
            this.addedToStage = true;
            this.video = new flash.media.Video();
            this.connection = new NetConnection();
            this.addChild(this.video);
        }
        private function onStreamNetStatus(event : NetStatusEvent) : void
        {
            switch (event.info.code)
            {
                case 'NetStream.Buffer.Flush':
                    if (this.paused)
                    {
                        this.paused = false;
                        this.stream.play();
                    }
                    break;
                case 'NetStream.Buffer.Full':
                    this.paused = true;
                    this.stream.pause();
                    break;
                case 'NetStream.Play.Stop':
                    this.paused = false;
                    this.connection.close();
                    this.stream.close();
                    this.video.attachNetStream(null);
                    break;
            }
        }
        public function cue(streamURL : String) : void
        {
            this.connection.connect(null);
            this.stream = new NetStream(this.connection);
            this.stream.addEventListener(NetStatusEvent.NET_STATUS, this.onStreamNetStatus);
            this.stream.client = this;
            // mute sound
            var newSoundTransform : SoundTransform = this.stream.soundTransform;
            newSoundTransform.volume = 0;
            this.stream.soundTransform = newSoundTransform;
            this.stream.receiveAudio(false);
            this.video.attachNetStream(this.stream);
            this.video.width = this.config.width;
            this.video.height = this.config.height;
            this.stream.play(streamURL);
        }
        public function onMetaData(info : Object) : void {}
    }
}

Sometimes this.stream.resume() has no effect on videos. The slideshow stops on a video and nothing happens : no event.info.code from onStreamNetStatus.

Any ideas ?

Thanks for your help.
