I've been unable to get playlists to transfer to my iPod from amarok. They appear to be transferred, and they show when I open them in gtkpod, but they're not there on the iPod itself. Also, any it erases my on-the-go playlist, as well as any saved ones I may have had. It's worked with a nano, but not with mine (30GB black video, I think 5.5 generation). Model number on it is MA446LL, in case you need that.

having exact same problem here; any help appreciated.
