When I first got my mac mini (2009) on Leopard and an ATV then I found that if streaming that the power saving would cut off my streaming connection.
As such I set my iTune Library to be shared out and connect to the shared library from the ATV over the wireless.
No longer did my movie drop out due to the mac going to sleep. Just had to ensure the mac was awake before turning on ATV.
I have since upgraded my mini to snow leopard and have the Time Capsule box wake the mini if the ATV tries to connect to the iTunes library.
Is now flawless, only difference is that instead of going to movies I goto Shared Movies instead but works great.
Network is Time Capsule, Mac Mini wired in, ATV in bedroom connected via Wireless.
