The new Apple TV 3 with 1080p HD gives you access to the best content — blockbuster movies, TV shows, sports, your music and photos, and more. You can even play content from your iOS devices on your Apple TV using AirPlay. However, the two biggest Apple TV limitations are the lack of codec support (like MKV, XviD, DivX, etc.) and not even having the ability to do basic surround sound like Dolby Digital 5.1.
