Logging into Youtube. curl maybe.

[The-Master]

I need a script which logs into youtube to view flagged videos. How do I do this. So far I have a script like this but it isn't working:

<?php

   $ch = curl_init();

   curl_setopt($ch, CURLOPT_URL,"http://www.youtube.com/login?next_url=/watch%3Fv%3DXcHyY9poq4w");
   curl_setopt($ch, CURLOPT_POST, 1);
   curl_setopt($ch, CURLOPT_POSTFIELDS,
        "username=whatever&password=whatever");

   $output = curl_exec ($ch);
curl_close ($ch); 

echo $output;
?>

Just now all I get out is the login form...
