My iTunes library has a tv series on it with 15 episodes. I have my ipod set to auto sync everything, but it only syncs 6 or so out of the 15. If i change it to manually syncing it and drag/drop the movies onto my ipod they sync fine. However, if i change it back to auto sync after all 15 are on it, it deletes the same ones as before? Any ideas on how to fix this?
