Dear Mr. Inthe,
  Yes, you're right, what I mean is capturing screen image of VCD Player. Unfortunately,The GetWindowDC(GetForeGroundWindow) and GetWindowDC(GetDeskTopWindow) function can only get the background color of the VCD images, but not the images.
   I suspect that the VCD images have the different format. ( perhaps I can send you the bmp file, if you don't mind )
   
Best Regards,
apin

*  I use Video CD PowerPlayer version 3.22 ( http://www.cyberlink.com.tw )

Hi I did what you are after over 18 months ago and found the only way was to use an Activex component that could sit infront of the video player and capture what was under itself.

This was an expensive option at $450US but it seemed the only way to win.

The reason that you are having trouble is that a video player or live video input puts the images to the front most Zorder of the screen.

If it helps the activex was the Pegusus
PhotoPro1.1 and was a worth while purchase at the time.
