Not sure what could be causing the problem. Your post was 5 hours before mine, perhaps YouTube changed something between then and now? I'd say try the command again and report back if it's still broken for you.

Edit: I just noticed something. All of your encrypted signature lengths are 83, 84, or 85, whereas mine are 85 or 86. I don't know what that means, if anything, but it could be something to look into.

Tried again couple minutes ago and, unfortunately, results are the same.
This time I dumped all intermediate pages (shared them here: https://www.dropbox.com/s/kye4foc2pabfnrh/Dumps.zip) and requests:

I cannot say that I am familiar with Python programming, but I'll try to investigate this issue by debugging source code today later.

Well, I've figured out how to debug source code of youtube-dl in Visual Studio and found out what was causing this problem.

First I thought that there might be something with my computer, so I tried to download this video on another computer, but result was the same. By the way, I have Windows 8 on the first computer and Windows Server 2012 R2 on the second computer. On previous versions of Windows, including Windows 7, Microsoft allowed users to choose their account name (I used my nickname), but on Windows 8 (and in some cases on 2012) it insist to create Microsoft account (otherwise Windows store won't work) and uses user's first name as account name, which in my case, obviously, is a bunch of Cyrillic characters ("Алексей", it's Russian name).

Apparently, this video contains obfuscated signature which requires youtube-dl to store some downloaded information in the cache. Default youtube-dl's cache directory in Windows is %USERPROFILE%/.cache\youtube-dl (C:\Users\Алексей/.cache\youtube-dl for both computers I used to test youtube-dl), but for some reason Python doesn't like non-ASCII characters in path (at least os.path.join function doesn't like them) and throws an exception.

Anyway, --cache-dir <path_that_contains_only-ASCII_characters> parameter works perfectly and resolves this problem.
