Description

WRITE DESCRIPTION HERE
I'm trying to download videos from cnbc.com. When I pass the URL of the page with the video to youtube-dl e.g. "http://www.cnbc.com/live-tv/jay-lenos-garage/full-episode/tough-enough/1594654787816" it falls back to the generic extractor instead of using cnbc.py. So I tried the video URL in the page, e.g. "http://player.theplatform.com/p/HNK2IC/8Mnloa_vQ1_x/select/media/guid/2304981409/4017204" then it says "This content requires a valid, unexpired auth token."
