    screen shot

    Normaly if I wanna take a screen shot of something in windows I just hit "prtscr" and paste in into paint. I noticed that you cant capture anything thats playing in windows media player (like a movie)!!! Is there any other way to do this or any utilities which will do it.

    also

    How can I capture all the sound output that go to the speakers from windows, dont be a dumb ass and say with a microphone cause that would suck.

    I am not that surprised. Almost certainly Windows Media Player is blocking the PrintScreen key.

    You could try using a screen capture program, but I wouldn't be surprised if WMP manages to block these two.

    Most screen capture programs work by calling an API function to read the video memory.

    Screen capture blockers work by hooking out such API functions are replacing them with dummy functions. I believe that there is even a patent on this, which is ridiculous.

    You need to find a screen capture program which reads video memory directly. Let me know if you find one.

    I think you have a back buffer which is represented by the screen's HDC. You draw to the back buffer and windows blits it when it sees fit. This means that any screen capture using the DC may not contain everything that's on the screen. OpenGL, DirectX etc.. draw directly to the video card and bypass the GDI backbuffer. Thus, no screen capture is possible from the DC. You'll need to hit the video memory directly, as Davros so eloquently mentioned
