You're using an outdated version of youtube-dl (and YouTube added the 92 signature only recently). Please update it, by typing

sudo youtube-dl -U

If the problem persists, please post the the output you get with youtube-dl v2013.07.17.1 or newer. Thanks!

Thanks, Phillip, it was my mistake with versions. It's worked with newest version.
