I'm considering an AppleTV (also considering a MIni, but that's another post). I have 2 Macs: 1 wireless on the first floor and 1 wired on the second. The first floor wireless has all the photos (though I could change that if needed). The second floor wired has a 750gb drive were I'll store all my video and iTunes. If I get an AppleTV I plan to locate it in the basement and hardwire it rather than deal with HD streaming. Question: how does syncing work and can I sync from 2 sources (photos from one and video from another)?
