MediaElement spielt Video nicht ab

Hallo liebe Windows Phone Freunde,

ich wollte mich heute mal an einer Media-App probieren und habe
dabei das Problem, dass ein Video nicht abgespielt wird.
Ich lasse mir den State auf einer TextBox ausgeben und wenn
ich das Video starte steht "Opening" und direkt danach (ohne
das das Video abgespielt wurde) "Closed".

Ich nutze folgenden Code:
