**ISSUE: youtube-dl only downloads the public-facing trailer videos**

Things to know:
1. adsrcourses.com requires credentials to login. I'm happy to provide them for the devs to investigate.
2. I can watch the videos just fine logged in from Chrome, but youtube-dl only downloads the teasers which are available to non-authenticated users.
3. I have tried to load in the cookies from Chrome and use the same Chrome user-agent as my browser. Passing the username and password also does not work.
4. It looks like from Fiddler that when in Chrome the client hello contains a session id and session ticket for the SSL handshake. youtube-dl does not send this information and is then sent the public video by the server.

How do I access the real videos from youtube-dl?
