I'm new to Apple TV. I am coming from the Boxee Box where I just put all my content on my readynas and put the share into Boxee and it found all my content. However now that I've switched to Apple TV, it seems like I have to have a computer with iTunes open all the time to "host" the media with Home Sharing even though all the content is on the nas. Is this the only way for this to work? Thanks!
