Hi, I’m using FLVPlayback component to show a video from the server. On a slow connection the video takes long time in loading even if the metadata is received (i get the onMetadata event fired). But still not even single/first frame of video shows. I get a blank white screen.

Here i also tried to show a preloader till enough of the streaming is done. But i’m not able to retrieve the bytesLoaded and bytesTotal values of the video. Any idea why the below code doesnot work?

```auto
FLVPlayer.addEventListener("progress", Delegate.create(this, progressHandler));

private function progressHandler(event:Object):Void
{    
      trace("bytes data " + event.bytesLoaded + " :" + event.bytesTotal);
}

```

I hv also tried these two but none of them work.

```auto
trace(FLVPlayer.bytesLoaded)

trace(FLVPlayer.getBytesLoaded())

```

It seems that the progressHandler() gets never called. Can anyone tell me how can i show a preloader in the video player?
