My set up: Old PC running Windows XP containing Itunes library New Macbook 40 G Apple TV 500 DVD Library I'd like to: Purchase an external hard drive that would allow me to store/back up my PC data and Itunes library as well as data from my Macbook and stream content to the Apple TV. I have looked at 1TB external hard drives, but I'd prefer a wireless network one. Ideas? Alternatives to Time Capsule? I'd eventually like to rip my DVD collection and store it as well. Thanks!
