I've been using a 2nd gen Apple TV for years now and was waiting for Apple to refresh the range for ages.
Finally got my new Apple TV on Xmas day and the first application is bought was Air Video HD for TVOS.. After all the years of using Air Video I really didn't mind the few quid to buy it again.
Great application the video is so much quicker and the latencies for playing etc. are all gone so big thumbs up for this version.
Watched my first 1080p 5.1 video last night very high quality viewing. Very happy..
