Hi, My dilemma: I would like to delete (some of) my music files from my Macbook, but keep them for use on my AppleTV. I have 100GB of music stored in itunes on my Mac-sync'd with the aTV. (If it helps with the legalities) they are all from original CD's..I have never purchased from itunes. I plan to use the AppleTV more .. perhaps looking at upgrading with aTV flash and adding an external hard drive? and I am assuming the Macbook would benefit from less on it's hard drive, but of course whenever I delete a track..AppleTV follows suit. I want to retain the option of syncing to add new files from the Macbook/CD's in the future of course. My set up: MacbookPro 160GB, apple tv 160GB, 500GB Time Capsule.
