My set up first: 3TB Time capsule 4TB WD NAS 3x ATV2 (all jail broken) Samsung Smart TV MBpro 2011 8gb ram Mac mini 2.7 ghz 8 gb ram Intend to use the MAC Mini as server. I have ripped all my dvd and blu's using MKV then iVI to convert into iTunes compatible keeping both formats until i decide which platform to use around the house. All ripped in 1080p so i want to stream HD. I do like iTunes, as very easy to transfer movies to iPhones (esp for the imminent arrival of my IP4s 64gb) and iPads for the kids and in the car etc but i am thinking in can select & keep the iTunes compatible movies on my MBpro hard drive!! Itunes? Plex? XMBC? i have installed plex on my Samsung Smart TV and installed plex and XMBC on the ATV2's give me some advise guys which platform to use?
