DVD library is no longer showing up in my Apple TV app

The library of the TV app on Mac (or PC) is a database file with all the content that has been added to the app, and their locations. The library is not the Media Folder location.

Your movie files from other sources, that have been added to the TV app library would be listed under Movies (if tagged as movie), or Home Videos (if untagged or tagged as home video), and also under Downloaded.

If the library database file has been reset, or moved and thereby unlinked/unfindable, then you may need to add the files again. There is an Add to Library menu item, or you can use drag-and-drop to the main area, when any library view is open in the app. Depending on your settings for the app, your added media files may be copied to a configured location, or else say where they are, if you have configured to not copy.

Note that the current TV app on Mac does support interlaced content, but the Computers app on the Apple TV box (Home Sharing) doesn’t. This may affect content originating from certain DVDs, in combination with the chosen conversion method.

The TV app on the Apple TV box doesn’t support Home Sharing.

Home Sharing on Apple TV will offer library video content in the Computers app instead. That is the only way, when using Apple’s software. It should show tabs along the top of the screen for various types of content that are shared for the selected library.

Verify that you have set the Mac to activate Home Sharing with the TV app’s video media library.

On modern versions macOS, that is in System Settings, not in the TV app.

Could your Computers app access to a library with just music be from a different computer? The Home Sharing library should bring together all supported shared content types.

** If more than one library is shared on your home network, then you should ideally recognize the name and know for which computer that is.

Thanks very much to both of you for this helpful thread. I had the same issue and this explanation has resolved the problem for me. I can access my own media through the computer app - it did take a while as i had a fairly large library.
