Hi,
I tried to download this video:

and this fails with the following (verbose) output:

Thank you for the report. Support for la7 has been added in youtube-dl 2014.01.27. It looks like you installed youtube-dl from pip or via your distribution's package manager. Use pip -U or your distribution's package manager to update.
