This is because MediaElement.NaturalDuration gives you a System.Windows.Duration object (<a href="http://msdn.microsoft.com/en-us/library/system.windows.duration(VS.95).aspx)">http://msdn.microsoft.com/en-us/library/system.windows.duration(VS.95).aspx)</a>, which in-fact doesn’t have a “CurrentState” member. However, MediaElement has a “CurrentState” member, so I think you intending that line to read “ if self.video. CurrentState == MediaElementState.Playing:”.
