Getting script error in YouTube Python download script

When I try to download the playlist with the youtube-dl Python script I get this error.

no fmt_url_map or conn information found in video info

Error no fmt_url_map or conn information found in video info with specific video explains the problem and so开发者_JS百科lution, but I don't know how can I apply the solution.

What do I need to do?

It works perfectly fine with videos:

$ git clone https://github.com/rg3/youtube-dl.git
$ ./youtube-dl  http://www.youtube.com/watch?v=VHkPiU9YAQk

Then you can play the video "VHkPiU9YAQk.mp4"

Also with playlists:

$ ./youtube-dl --playlist-start=1 --playlist-end=1 http://www.youtube.com/my_playlists?p=AA0F3A8E116E1219

Check the parameters you are using.
