I thought maybe this was #662, but that was patched months ago, and it says it's the newest version (from the future!)

$ youtube-dl -U
youtube-dl is up-to-date (2013.06.29)

Thanks for the report. This will be fixed in youtube-dl 2013.06.30 (Some parts of our Windows build system only support numerical values, so the version number can outrun the date if we release multiple times during one day). Use sudo youtube-dl -U to update.

@phihag The problem here is actually that for videos with age restriction, the ytplayer.config is missing. And BTW, it seems that the encryped signatures have been extended for more than Vevo videos
