ARISE answer! and serve your master

OK, I've figured out how to work this. I'm sure I'm not doing it the completely correct way but it does work.

Here is the code-behind of a WPF application, with a Pause/Play button.

public partial class Main : Window
{
    MediaPlayer MPlayer;
    MediaTimeline MTimeline;

    public Main()
    {
        InitializeComponent();

        var uri = new Uri("C:\\Test.mp3");
        MPlayer = new MediaPlayer();
        MTimeline = new MediaTimeline(uri);
        MTimeline.CurrentTimeInvalidated += new EventHandler(MTimeline_CurrentTimeInvalidated);
        MPlayer.Clock = MTimeline.CreateClock(true) as MediaClock;
        MPlayer.Clock.Controller.Stop();
    }

    void MTimeline_CurrentTimeInvalidated(object sender, EventArgs e)
    {
        Console.WriteLine(MPlayer.Clock.CurrentTime.Value.TotalSeconds);
    }

    private void btnPlayPause_Click(object sender, RoutedEventArgs e)
    {
        //Is Active
        if (MPlayer.Clock.CurrentState == ClockState.Active)
        {
            //Is Paused
            if (MPlayer.Clock.CurrentGlobalSpeed == 0.0)
                MPlayer.Clock.Controller.Resume();
            else //Is Playing
                MPlayer.Clock.Controller.Pause();
        }
        else if (MPlayer.Clock.CurrentState == ClockState.Stopped) //Is Stopped
            MPlayer.Clock.Controller.Begin();
    }
}

The trick is that once you set the clock of a MediaPlayer, it becomes clock controlled, thus the use of MPlayer.Clock.Controller to do all of the controlling :)
