I use Plex as my media server .. I have a Mac Mini downstairs which never turns off and the Plex server runs on it. I then have the Plex Home Theater Client on the same machine for viewing the files, I also have Plex on my iPhone for Music & Xbox One. I have a Roku box in one bedroom which acts as a Plex client also. However, for all 'home' access media. Can I just copy all of video files into iTunes and use iTunes home sharing? If I do this will they be accessible to say an Apple TV? If yes id rather buy Apple TVs for the bedrooms as it means I can also Airplay to them .. Roku is great but I like the Apple Ecosystem plus the interface is nicer .. Just not sure if it works! - Also if I copy all my movies to iTunes does it just copy a mirror rather than the entire file? I have 2TB of videos, I don't particularly want 4!
