Hi, Got an ATV 40gb today (yeah it was cheap). Cool wee device but god it's laggy as hell. At times its completely unusable due to the interface lag. I'm pretty sure it's not doing much in the background, it should have had plenty of time to index the library since I synced it 6 hours ago. Any hacks or tricks to speed it up? Streaming from iMac 2.8 / 360gb itunes library / latest itunes / no movies synced / Gigabit ethernet connection.
