Encrypted signatures, unable to download video

Getting this error:

 Encrypted signatures detected.
ERROR: unable to download video

And -v shows

Traceback (most recent call last):

UnavailableVideoError

However, the video is most definitely available (through Firefox, at least)

This is with 2013.08.02 release.

Is YouTube yet again doing something wacky?

Try updating to the new version sudo youtube-dl -U, if it still fails, post the url of the video that fails

Works as of 2013.08.17 version, thanks!
