Setting the stage - I live in a studio apartment, and have an older tube TV. Will eventually replace it with a new flat-screen HDTV, but for now, it's what I have. I also have an older stereo system which is hooked up to the TV. What I want to do - stream both music and video from my macbook air to the tv/stereo. This content could be from my iTunes library, from dvds that I rent or own, or from TV shows over the internet (i.e., hulu). Plus, youtube videos, if possible. (I don't have cable or network subscriptions and can live w/out them.) From what I have read, what I want can be done with apple tv (with appropriate converters/adaptors for the older equipment) and airplay. Am I understanding correctly? Any hints or recommendations? Thanks in advance! Having avoided commercial TV for several decades, I am more than a bit lost in many of the conversations I read!
