Description

Trying to pull videos from NBC website I get the above error. I log in to the site in my browser using my DirectTV login info, verify the video can play, and copy the link to use with youtube-dl. I've been able to use the cookies.txt chrome extension to pull from HGTV after logging in with my DTV info, but it doesn't work with NBC. Let me know if you want to see that output.

I believe that there is a URL change or something with the MSO. If you're off the ISP IP space, you get the 401 unauthorized. If you're on their network, ERROR: Unable to extract post url

[ds1018]

I signed up for an NBC universal account so it wouldn't deal with the DirectTV login info and I'm getting the same errors.

Anyone have any experience with using YouTube-dl to pull from the NBC website?

I believe it is the same issue as here: #26139
