I had read a fair bit of negative feedback about ATV4 and delayed buying one until now. I use a 2009 Mac mini with Plex, media on a synology diskstation all connected by ethernet. I must say I really like the ATV4. I'm using Infuse instead of Plex which has poorer library and server functionality, but seems to play Dolby TrueHD and DTS/ DTS-hd by pass-through to my AV amp. The remote is really good for scrubbing through scenes. Hopefully Siri will soon work with Infuse. Playback is completely stutter-free. I'm probably going to stop using the mac mini as a HTPC.
