How to take a screenshot or record video on the fourth-generation Apple TV

Serenity Caldwell posted a nice tip for taking a screenshot or recording video on the new Apple TV. It's really more of a tip for developers than casual users as it requires connecting your Apple TV to your Mac with a USB-C to USB cable to record video, and the addition of Xcode for screenshots.

Serenity also points out:

You won't be able to use these commands or controls for any copyrighted or DRM-laden content; try to do so, and you'll just see a blank, black screen.
