When loading up material on my nano, iTunes keeps adding playlists that I don't have checked. It seems like if I add a file that happens to be in a given playlist, it adds that playlist to the iPod (but not everything in that playlist, just the playlist itself and the files I have selected) even if it's not selected. For example, I don't have the Purchased playlist checked, but if I add a movie that is in that playlist, it adds that playlist to the iPod and I can't get rid of it. I've seen this mentioned online elsewhere, but no fix. Anyone know why it's doing this and how to make it stop?
