I am a premium YouTube member. I have purchases I would like to download. It completes but I get an error (unable to extract video data.) I tried DVR but I get a video asking to login or signup to verify my age.
YouTube Movies requires the DVR to capture.
Open the DVR
Navigate to YouTube.com and login
The Navigate to the movie, play it and click REC
Ok, I tried to sign in and it wouldn't let me.
It looks like the Chrome version the DVR uses is Version 75.0.3770.142 (Official Build) (32-bit). It does ask me to update it but I didn't.
How am I supposed to use the DVR if I can't login to YouTube?
Thats strange. I can login here just fine. Where does that "Learn more" link take you?
Anyway you can spoof the browser by settings the user agent string in Settings > DVR > User Agent Override
You can set it to something like
