Yep, seeing the same thing. Only appears to be VEVO vides, so probably merge this with https://github.com/rg3/youtube-dl/issues/1258

I'm not a big fan of VEVO or their videos, and could easily live without ever watching any of their stuff, but people occasionally send me stuff to look at, and this is one of those, FYI.

I see a pattern here, over the past few weeks, and I'd venture a wild guess that VEVO is lobbying/threatening/paying Google to get them to lock down YouTube and copy-protect their videos. I suspect that this is the beginning of the end of access to YouTube. I don't see this ending well.

I hope I can make the signature download automatic today. In the meantime, v2013.08.17 should fix this issue.
