Description of problem:
When i was trying to download the video from youtube, by specifying the format whith the line:
youtube-dl -F 43 http://www.youtube.com/watch?v=eYO1-gGWJyo

It's seem to not work, the "-F 43" is for specifying the format, but this give us:

$ youtube-dl -F 43 http://www.youtube.com/watch?v=eYO1-gGWJyo
WARNING: The url doesn't specify the protocol, trying with http
