I did it from IP 74.103.153.57 in Doylestown, PA, USA and there constantly is that error. In 5 min I test the same URL from Ukraine. But when I tried to do the same from IP 95.133.153.236 in Ukraine, there no error occurs. There youtube-dl works great as a version #2013.07.08.1 as version #2013.08.08.1 :

This issue is fixed in 2013.08.09.
Update youtube-dl using youtube-dl --update

[mokko]

I tried it and you're right, so I guess we can close this issue. Thanks for quick response!
