Why not use Wantyoutube.com

Wantyoutube (and MORE) is a popular website to save and download Tudou and Youtube videos. It is so convenient because the only act you need to do is insert a word "want". You have to try it!

For example:
Youtube - http://www.youtube.com/watch?v=iCtZ8EMVJ60
change to - http://www.wantyoutube.com/watch?v=iCtZ8EMVJ60

Tudou - http://www.tudou.com//alM0tqYD-ig/x
change to - http://www.wanttudou.com//alM0tqYD-ig/x
(PS: Tudou is a Chinese video-sharing website.)
