So i'm a little confused about how airplay works. i know you must have an apple tv for it to work. and that some apps on the ipad you can use 'airplay' to watch content from your ipad to your apple tv.. well does anybody know if netflix app on the ipad has the airplay function so i can use my ipad to watch netflix instead of buying a ps3, xbox 360, roku ect? also, is it possible to stream movies from my computer (AVI, MKV, DIVX ect) using the ipad and airplay? or is this not possible? i know that with air video i can watch movies from my mac on my ipad.. but if i were to stream movies from my ipad to tv using air video.. can i use airplay? or is my only option is to buy and use the hdmi cable that allows mirroring with the new ipad. also.. with the HDMI cable that does mirroring.. does anybody know or read if audio will pass thru the hdmi cable as well?
