About the library on tvOS, I don’t understand the sync.
On my iPhone, I’ve downloaded 12 movies from my local NAS, so there’re in my Infuse iOS Library, but on my Apple TV the library is empty, I’ve just the NAS Folder for stream. It’s impossible to download movies from NAS to Apple TV ?
Apple TV doesn’t support downloading files to the Apple TV.
Okay, but finally, what’s the goal of the Library on Apple TV ?
Maybe this will help.
Just make sure you connect with SMB, NFS, FTP/SFTP, or WebDAV and not DLNAUPnP.
Library won’t be available when using most DLNA/UPnP devices.
