Hello and thanks in advance to all that reply. Here is the set up I want to do. Does anyone know how to do it? I have one external hard drive where all my media is stored. That drive is shared via Airport Extreme usb port and I can see it from my macbook and my pc. My macbook is the computer where I stream to Apple TV from. The problem is I travel alot and take my macbook with me. When I leave, the wife and kids don't have access to apple tv if my macbook is not home. Can I set up apple tv to stream my library from my pc? This way, when I travel and take my macbook, the wife and kids can still see the media on apple tv. BTW, on the macbook I am running latest versions of Snow Leopard, iTunes and apple tv. On the pc I am running windows XP home edition. Thanks.
