Description of your issue, suggested solution and other information

Some NBC videos require Adobe authorization, which is currently not supported.

FYI: https://github.com/rg3/youtube-dl/blob/master/README.md#adobe-pass-options

[gkoelln]

Yes, I'm aware of the option, thank you, but when I add my locally updated MSO:

So, it's not even trying to authenticate, or get an auth token.

[gkoelln]

So, IMO, we need to add the authentication to either NBC or theplatform. It's just a bit above me, or I'd do it myself.

[yan12125]

Oops, I forgot you're the author of Dish authenticator. Yes nbc.py needs an update.

Thanks!
