Here is my code;

        public MainPage()
        {
            InitializeComponent();

            // Set the data context of the listbox control to the sample data
            DataContext = App.ViewModel;
            this.Loaded += new RoutedEventHandler(MainPage_Loaded);
        }

        // Load data for the ViewModel Items
      private void MainPage_Loaded(object sender, RoutedEventArgs e)
        {
            if (!App.ViewModel.IsDataLoaded)
            {
                App.ViewModel.LoadData();
            }
        }

        private void ListBox_Loaded(object sender, RoutedEventArgs e)
        {
            WebClient Andbeyon = new WebClient();

            Andbeyon.DownloadStringCompleted += new DownloadStringCompletedEventHandler(Andbeyon_DownloadStringCompleted);
            Andbeyon.DownloadStringAsync(new System.Uri("http://gdata.youtube.com/feeds/api/videos?author=gyanandbeyond&v=2&alt=json", UriKind.Absolute));

        }

        void Andbeyon_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e)
        {
            var response = e.Result.Replace("$", "dlr");
            var jsonData =  JsonConvert.DeserializeObject<rootobject>(response);
            var src = jsonData.feed.entry.ElementAt(1).mediadlrgroup.mediadlrplayer.url;
            MediaPlayerLauncher player = new MediaPlayerLauncher();
            player.Media = new System.Uri(src, UriKind.Absolute);
            player.Controls = MediaPlaybackControls.All;
            player.Orientation = MediaPlayerOrientation.Landscape;
            player.Show();
        }
        
    }
}
