Off topic: Unfortunately atv is a piece of **** for playing movies: poor support for differend formats. Once you try to play mkv files without exactly format for atv you get troubles. I wouldnt spend any real money to this carbage.
It's kinda ridiculous to rage out about their support of a popular piracy format. If you're ripping your own digital copies, MP4 works just fine. and it's also great for Netflix and iTunes Store. Plus you can AirPlay from any other Apple device. Heck you can AirPlay vlc from your computer and watch pretty much whatever format.
Anyway, there are plenty of options out there between chromecasts and rokus and whatever else. By all means get the one that suits your needs best, its just silly to say something is objectively crap because it doesn't suit your specific usage needs.
