### Description of your *issue*, suggested solution and other information

The watch.cbc.ca website does a region verification hence the use of the proxy in the command line above.  Using that proxy and the below credentials I am able to view that video and others just fine.   The login (available on bugmenot.com) is:
username:  q973391@mvrht.net
password:  q973391@mvrht.net
When logged in as the user: q973391@mvrht.net on a web browser I can view videos fine using a http/https proxy.

You can register for free on the cbc site and I do have another login that I've also used successfully in a browser to view the video in the above attempt but also does not work from the CLI using youtube-dl.  

Oddly, this video on the cbc site works fine even without using the proxy or user login:

$youtube-dl https://watch.cbc.ca/media/baroness-von-sketch-show/season-3/episode-1/38e815a-00f310e1384

Thanks for all the great work!  I find youtube-dl to be an indispensable tool!
