Hello, I suppose the question portion of this is: is VRV supported\compatible? I did try and perform a .\youtube-dl.exe --list-extractors in which case VRV and VRV:SERIES did show up however I have not had much success.

 I am trying to download episodes\video files from VRV [https://vrv.co] For example: [https://vrv.co/series/GR751KNZY/Attack-on-Titan]  I have tried just passing in the URL as the content should be viewable with just a regular user account, but also passed in my premium account creds and or a cookies.txt and user agent (I've tried individually as well as different combinations)
