Working with unsupported sites (Codeschool)

I guess my problem is all about unsupported extractor that you might include in package in future releases. Here is the output though

I wish I had enough knowledge to make the extractor myself, then I would not had bothered you and rather had helped you instead.

Duplicate of #4810. See https://github.com/rg3/youtube-dl/blob/master/README.md#developer-instructions if you're going to write your own extractor.
