Попробуйте следующий код
MainPage.xaml.cs
namespace MediaSample
{
public partial class MainPage : PhoneApplicationPage
{
// Constructor
public MainPage()
{
InitializeComponent();
progress.DataContext = this;
this.Loaded += new System.Windows.RoutedEventHandler(MainPage_Loaded);

}

{

{

ThreadPool.QueueUserWorkItem(o =>
{
while (true)
{
Dispatcher.BeginInvoke(new Action(() => Progress = mediaplayer.Position.TotalSeconds * 100 / Duration));
Thread.Sleep(0);
}
});
}
}
void mediaplayer_BufferingProgressChanged(object sender, System.Windows.RoutedEventArgs e)
{
MediaElement mediaplayer = sender as MediaElement;
if (mediaplayer.BufferingProgress == 1)
Debug.WriteLine(mediaplayer.NaturalDuration);
}
void MainPage_Loaded(object sender, System.Windows.RoutedEventArgs e)
{
mediaplayer.Source = new Uri("/Oru nalum..mp3", UriKind.Relative);
mediaplayer.Play();
}
public double Progress
{
get { return (double)GetValue(ProgressProperty); }
set { SetValue(ProgressProperty, value); }
}
// Using a DependencyProperty as the backing store for Progress. This enables animation, styling, binding, etc...
public static readonly DependencyProperty ProgressProperty =
DependencyProperty.Register("Progress", typeof(double), typeof(PhoneApplicationPage), new PropertyMetadata(0.0));
}
}
