Unable to capture a video using robot.createScreenCapture

Question

Hi all,
I'm having one problem with robot.createScreenCapture, i used the
below code to take screen shot, everything goes fine except one case, I'm unable to capture videos played in windows media player & winamp, black screen is displaying instead of the video. I used avi files.
here is the code
import java.awt.AWTException;
import java.awt.Dimension;
import java.awt.Image;
import java.awt.Rectangle;
import java.awt.Robot;
import java.awt.Toolkit;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import javax.imageio.ImageIO;
import javax.swing.JButton;
import javax.swing.JFrame;
public class CaptureImage implements ActionListener {
     Robot robot = new Robot();
     Image image = null;
     public CaptureImage() throws AWTException {
          JFrame frame = new JFrame("Capture");
          JButton button = new JButton("Capture");
          frame.setAlwaysOnTop(true);
          button.addActionListener(this);
          frame.getContentPane().add(button);
          frame.pack();
          frame.setVisible(true);
     public void actionPerformed(ActionEvent e) {
          // image = robot.createScreenCapture(new Rectangle(800, 600));
          String outFileName = "shot.png";
          // determine current screen size
          Toolkit toolkit = Toolkit.getDefaultToolkit();
          Dimension screenSize = toolkit.getScreenSize();
          Rectangle screenRect = new Rectangle(screenSize);
          // create screen shot
          Robot robot;
          try {
               robot = new Robot();
               BufferedImage image = robot.createScreenCapture(screenRect);
               ImageIO.write(image, "png", new File(outFileName));
               System.out.println("Saved screen shot (" + image.getWidth() + " x "
                         + image.getHeight() + " pixels) to file \"" + outFileName
                         + "\".");
          } catch (IOException e2) {
               e2.printStackTrace();
          } catch (AWTException e1) {
               e1.printStackTrace();
     public static void main(String[] args) {
          try {
               new CaptureImage();
          } catch (AWTException e) {
               e.printStackTrace();
}

Are you setting the videoPause property to true in the rule you're using to navigate to the video screen? For example, assume you're using a button to navigate to the VideoScreen, its OnSelect property should be: Navigate(VideoScreen, ScreenTransition!Fade,{videoPause:false}).
Basically, the value needs to change for the video to pause. If you don't have that set up, you could also do that within the rule you're using to navigate to scrHome as follows:  
UpdateContext({videoPause: false});Navigate(scrHome, ScreenTransition!Fade,{videoPause: true})
