quick question-- I have a recent generation video ipod (5th or later) I think. I have a LOT of playlists I've manually created. Any way to add playlist subgroups (or folders) within the ipod so I can categorize them for simplicity?I read somewhere that is possible if you do complete automatic synching. But I really don't want to start all over again if at all possible. A workaround or trick you know of would be great. Thanks!
