Fyi people here will deny your claim because it "works great for them".

Hopefully some day google straightens this device out...

When you have issues with specific videos, you can report it by using the "feedback" button in the OSD:

1. Press any button.
2. Press up to move to the icons
3. Press the "more" button to show the rest of buttons
4. Move to the second last button, the "feedback" button, next to the "stats for nerds" button and press it.
5. Select the option related to the issue.

You can also use the YouTube Feedback website to report issues with videos, with the app itself or to request features.
