[carpatos]

Hello guys!
I can´t download this video:
https://www.youtube.com/watch?v=_RXdJf8ZNvQ
I can download others video from this YouTube channel (Olympics) even with Windows 8.1 simple apps, but not that.
I´ve tried it with atube catcher (stream catcher), url snooper, replay media, etc. but it has been impossible.

Can someone help me?
Thanks in advance.

note: ip address has been modified.
Is this right? It is not the same like yours hasomaso.
How can you get the m3u8 url and how can i do it?
Thanks.
