Using PortControl Interface problem????

Question

I am trying to write a program that captures video from my TV tuner composite port , using the following code:
import java.awt.Component;
import java.awt.Frame;
import java.io.IOException;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.media.CannotRealizeException;
import javax.media.Manager;
import javax.media.MediaLocator;
import javax.media.NoDataSourceException;
import javax.media.NoPlayerException;
import javax.media.Player;
import javax.media.control.PortControl;
import javax.media.protocol.DataSource;
import javax.swing.JOptionPane;
* @author Zaid
public class Crap {
    public static void main(String args[])
        Player player;
        Frame frame = new Frame("Test");
      try {
            JOptionPane.showMessageDialog(null, "begin the device capturing");
            MediaLocator ml = new MediaLocator("vfw://0");
            if(ml == null)
                JOptionPane.showMessageDialog(null, "No MediaLocator created");
            else
                JOptionPane.showMessageDialog(frame, ml.toString());
            DataSource ds = Manager.createDataSource(ml);
            // getting the port Control
            Object[] c_list = ds.getControls();
            for(int i=0; i<c_list.length; i++)
                JOptionPane.showMessageDialog(frame, c_list.toString());
try {
player = Manager.createRealizedPlayer(ds);
JOptionPane.showMessageDialog(null, "player created successfully");
if (player.getVisualComponent() != null) {
frame.add(player.getVisualComponent());
player.getVisualComponent().setSize(300, 300);
if (player.getControlPanelComponent() != null) {
frame.add(player.getControlPanelComponent());
if (player.getControl("javax.media.control.PortControl")!= null) {
PortControl pc = (PortControl) ds.getControl("javax.media.control.PortControl");
pc.setPorts(PortControl.COMPOSITE_VIDEO);
JOptionPane.showMessageDialog(null, "PortControl Found");
frame.add(player.getControl("PortControl").getControlComponent());
else
JOptionPane.showMessageDialog(frame, "PortControl not found!!!");
player.start();
//audioPlayer.start();
frame.setVisible(true);
frame.setSize(300, 300);
} catch (CannotRealizeException ex) {
Logger.getLogger(JMFtest.class.getName()).log(Level.SEVERE, null, ex);
} catch (IOException ex) {
Logger.getLogger(JMFtest.class.getName()).log(Level.SEVERE, null, ex);
} catch (NoPlayerException ex) {
Logger.getLogger(JMFtest.class.getName()).log(Level.SEVERE, null, ex);
} catch (NoDataSourceException ex) {
Logger.getLogger(Crap.class.getName()).log(Level.SEVERE, null, ex);
JOptionPane.showMessageDialog(frame, "No DataSource found");
} catch (IOException ioe) {
System.out.println("Damn exception: " + ioe);
but PortControl always give that value of null
the reason is  PortControl Interface is not implemented in the JMF
How to implement it ???
Is there any other way to capture TV tuner video from composite port???
Thanks in
