I'm doing a little experimenting with my GMA 950 2 gHz Mac Mini. I'm seeing how it behaves as an ATV server as the sync computer. However, it is set to sleep after an hour of inactivity, at which time it disappears from the network and none of the other computers can see it in a Finder pane and the non-sync'd content disappears from the ATV's menus. I have wake on network activity enabled, but that does not seem to be functional. Surely I don't have to have it set to never sleep?
