Long time lurker, first time poster... (Yes, I've run searches on this, and looked over on AppleTVHacks.net in detail) What I want to have (woking properly): Music Content Stored entirely on the ATV. But I need the conditions below to be met also... Must be able to play on the ATV (i.e. through Home Theater). Must be able to stream to my iMac for playing in another part of the house. Must be able to add new tracks to the ATV, and update meta info on the tracks from time to time. Must be able to use the one library & update play counts, etc What I was thinking is to change my Mac iTunes Library to access all the audio files from the ATV - stored in /Volumes/Media/Media Files - and deleting the ones on my local iMac and then hitting Sync. However, I get the funny feeling if i do that, the ATV will not like it, and may lose my 6000 odd songs I once spent a week ripping... FYI, I have hacked the ATV, and enabled SSH, installed programs and all that jazz and can access all volumes from remote machines. Any ideas on the right solution?
