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.
Try using a different browser. If you’re already using a supported browser, you can refresh your screen and try again to sign in.
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
Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/86.0.4240.111 Safari/537.36
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.
