I am considering getting an Apple TV after the recent movie rental announcement. From what I recall when Apple TV was introduced, music and movies can only be synced to the Apple TV. You cannot manually manage the content. Is that still true? I am looking to use the Apple TV to host/store music from three different iTunes libraries. Each library is on a separate computer. The computers are not always present or on where the music can be streamed. Can I combine the different libraries on the Apple TV without moving all of the music to one computer? I do not really have the drive space for this? Thanks in advance.
