So We have a few macs and an airport, tons of moves on our respective drives, a few more on DVDs we can't copy due to whatever... and a few itunes libraries of music. I would like to move my movies on my laptop to an external drive that sits off of airport. And I would like to put a DVD in my computer and stream it to my TV. And all that other good stuff. Most conversations are a few steps ahead of where I am now. I can't figure out what Apple TV would cover and where its limitations are. Or any other alternative for that matter. So is there is good, basic rundown of what I can do with Apple TV (that isn't from Apple's shiny, one-sided web site)? Thanks!!
