You should have made the Airplay bit at the end more prominent, because it gets lost like its an afterthought but its an important point. Playing from the AppleTV, not Airplay, however does require the correct format. Using Airplay (for me at least) is worst than playing from the AppleTV tho. I rather not put up with Airplay streaming because it never displays my whole iMac (21.5") screen correctly and then you have to manually select the sound output. But it is great as a backup (have to leave the monitor on though when using Airplay)
