Description of your issue, suggested solution and other information

Is there a way to support the download of Tudou and Youku channels? I'm an archivist, and i upload channels to Internet Archive (archive.org). There have been a couple i've been trying to archive, and if youtube channel support was implemented, then Youku/Tudou should be no problem. thank you. :)
