WPF VideoCaptureElement doesn't display and flash on and off

I used the SampleApplication which is provided with the WPF MediaKit Library to display a WebCam stream on a VideoElement.This code works well except for one specific computer on Windows XP Service Pack 3 (quite old).

The Webcam is initialized (LED is on) but the VideoElement flash on and off (became black) when an another UIElement is pressed (menu element for instance) or stay white in other cases. This behavior is really weird.

Have you any ideas how to solve it? Is it a library issues or something like that? Is there a known bug fix?

 

EDIT : It seems run when the project is compiled with the .Net Framework 3.5 but not with the 4.0 Full.
