<MediaElement Name="Media" Source="video.mp4" MarkerReached="Media_MarkerReached" />
<TextBlock Name="txOutput" />

private void Media_MarkerReached(object sender, TimelineMarkerRoutedEventArgs e)

    txOutput.Text =
        string.Format("{0},{1},{2}", e.Marker.Time, e.Marker.Text, e.Marker.Type);
}
