If the code above doesn't works and if it gives a warning like "Invalid parameters" then Copy and Paste the Code Below to your Address Bar:

javascript:window.location.href = 'http://youtube.com/get_video?video_id=' + swfArgs['video_id'] + "&l=" + swfArgs['l'] + "&sk=" + swfArgs['sk'] + '&t=' + swfArgs['t'];
