For example, mpeg4 movie currently is popular. But it is a bad idea to let CPU to do Motion-Comp. So the movie image should be rendered by video card to video ram. We have many surfaces in video card, including VGA, video, etc. Just like TonyN said. It seems the screen capture of Linux will not access the video area.

No, actually it's magic. Or just about, as the video card is compositing the video onto the regular desktop using a color key. At least, that's how it was done on MacOS some years back. Probably doing accellerated decoding on the video card. ____________________________________________________________________ TonyN.:' <a class="moz-txt-link-rfc2396E" href="mailto:tonynelson@georgeanelson.com"><mailto:tonynelson@georgeanelson.com></a> ' <a class="moz-txt-link-rfc2396E" href="http://www.georgeanelson.com/"><http://www.georgeanelson.com/></a> </pre> </blockquote> </body> </html>
