I have a MediaElement that is reporting its position incorrectly and weirdly, but consistently. It seems like when it gets to the last second of the audio (and it's always the last second, regardless if the sound is two seconds or 10), it doesn't update it's position until it finishes.

Example output:

Playback Progress: 0/3.99 - 0 Playback

Progress: 0.01/3.99 - 0 Playback

Progress: 0.03/3.99 - 0 Playback

Progress: 0.06/3.99 - 1 Playback

Progress: 0.07/3.99 - 1 Playback

Progress: 0.08/3.99 - 2 Playback

Progress: 0.11/3.99 - 2 Playback

Progress: 0.14/3.99 - 3 Playback

Progress: 0.19/3.99 - 4 Playback

Progress: 0.23/3.99 - 5 Playback

Progress: 0.25/3.99 - 6 Playback

Progress: 0.28/3.99 - 7 Playback

Progress: 0.3/3.99 - 7 Playback

[SNIP]

Playback Progress: 2.8/3.99 - 70

Playback Progress: 2.83/3.99 - 70

Playback Progress: 2.88/3.99 - 72

Playback Progress: 2.9/3.99 - 72

Playback Progress: 2.91/3.99 - 72

Playback Progress: 2.92/3.99 - 73

Playback Progress: 2.99/3.99 - 74

Playback Progress: 3/3.99 - 75

Playback Progress: 3/3.99 - 75

Playback Progress: 3/3.99 - 75

Playback Progress: 3/3.99 - 75

Playback Progress: 3/3.99 - 75

Playback Progress: 3/3.99 - 75

Playback Progress: 3/3.99 - 75

Playback Progress: 3/3.99 - 75

Playback Progress: 3/3.99 - 75

Playback Progress: 3.99/3.99 - 100

That is the result of:

    WriteLine("Playback Progress: " + Position + "/" + LengthInSeconds + " - " + (int)((Position / LengthInSeconds) * 100));

    public double Position
    {
        get
        {
            return my_media_element != null ? my_media_element.Position.TotalSeconds : 0;
        }
    }

    public double LengthInSeconds
    {
        get
        {
            return my_media_element != null ? my_media_element.NaturalDuration.TimeSpan.TotalSeconds : 0;
        }
    }

Anyone have any ideas why this is occurring?
