Hi, gibigbig,

Try this code:

$embed='function setembedcode(cwidth,cheight)
{
  
  document.getElementById(\'embedcode\').value = \'<object width="\' + cwidth + \'" height="\' + cheight + \'"><param name="movie" value="http://www.megavideo.com/v/ZDWFCCMEf5a91463ba9f5539ffffde18eaa9acbf"></param><param name="allowFullScreen" value="true"></param><embed src="http://www.megavideo.com/v/ZDWFCCMEf5a91463ba9f5539ffffde18eaa9acbf" type="application/x-shockwave-flash" allowfullscreen="true" width="\' + cwidth + \'" height="\' + cheight + \'"></embed></object>\';
  
}';
preg_match_all( '#(http\://)?(w{3}\.)?megavideo\.com/v/([a-z0-9]+)#im', $embed, $matches, PREG_SET_ORDER);    
$matches=array_unique($matches);
    foreach($matches as $txt){
        echo 'http://www.megavideo.com/v/'.$txt[3].'<br />';
    }
