I’m trying to build a Dynamic Video Playlist based off of this article: [http://www.adobe.com/devnet/flash/articles/video\_playlist.html](http://www.adobe.com/devnet/flash/articles/video_playlist.html)  
and all I’m trying to do is change movie file names to my streaming service, but I keep getting the following error:

```auto
Error #2044: Unhandled AsyncErrorEvent:. text=Error #2095: flash.net.NetConnection was unable to invoke callback onMetaData. error=ReferenceError: Error #1069: Property onMetaData not found on fl.video.ConnectClient and there is no default value.
