Apologies if this has been covered but I can't seem to find it anywhere. I have over 500 DVDs encoded and in iTunes on my Home Network with Apple TV3, Windows PC and external 4TB HDD. This all works fine, however I would like to take a backup of my iTunes and another ATV3 and set these up at my girlfriend's house. She does not have internet, but I wanted her to be able to have a backup copy of my iTunes library so she can watch my films via her own Windows laptop, ATV3 and external HDD. Is it possible to set this up and have it working without the Internet? Any help would be greatly received.
