Is there any plan to add native support to 4K video streaming which is made with XAVC/XAVC S video codec? For example, my home video is shot on Sony FDR AX100 camcorder which utilizes above mentioned codec with up to 100 Mbps bitrate. I shoot in FullHD and 4K mode. FHD movies are streamed to Apple TV without any problems but any 4K video is streamed only for a few seconds, then it interrupts for several seconds for caching, then restarts and so on. Actually it is not possible to watch my 4K home videos because of this pauses. No need to say that all Blu-Ray 4K videos are streamed without problems.
