for me, airplay mirroring is not smooth, i get some lag. movies is only just about watchable, but noticeable lag. whats needed for the kind of airplay mirroring that i'v seen others get where films play 100% smooth? i mean, when i watch the same movies through itunes airplay, they play 100% smooth. at the moment, im on 10mb broadband. i have 2011 late 15 inch mbp. i dont have an ssd yet, but it will be installed when it arrives next week. is there any settings that could make airplay perform less based on my router or network??
