Movies with 5:1 audio on Mac Mini
I have plenty of movies saved on my Time Capsule that have audio 5:1 Dolby DTS etc. When I play them from my Mac Book Pro and its iTunes via Apple TV, since ATV has an optical output I connect it to my Cinema Surround DENON amplifier and I can enjoy the sorround effects.
Problem is that when I am not home th rest of the family has only iPads and cannot access the movies that are on the TC. My idea is to buy a Mac Mini so that when I am not home they can access the movies on the TC via the Mac Mini, but the question is: how I can enjoy the 5:1 audio surround using Mac Mini only? I guess I will have to connect the Mac Mini to the ATV, but via Airplay or via cable?
I will appreciate any suggestion to make best set up to enjoy the movies from TC including the 5:1 audio.
