Video throwing exceptions

Jun 28, 2012 at 3:13 PM

Hi, I really like WPF MediaKit but sometimes it does not show video.  I tried to repair it but I have not succeeded. Every time it happened, a lot of internal exceptions has been thrown:

 

System.InvalidOperationException:

Cannot call this method without a back buffer.

Stack trace:          at System.Windows.Interop.D3DImage.AddDirtyRect(Int32Rect dirtyRect)

 

Do You have any idea, how to repair it?

I am using two instances of MediaUriElement at one time, playing the same video.
