Ok, maybe I'm missing something fundamental here. I expect that when I press the genius button on a song on the Ipod, it'll suggest a playlist like it does in Tunes. The problem is when I do that, I'm told that "Genius playlists are not enabled. Use iTunes to enable Genius Playlists." As far as I'm aware, I've enabled Genius in iTunes. How can I get the iPod to use them also?? I've attempted to disable Genius, then enable it, and then force the update. All that seems to work, but it doesn't seem to be getting to the iPod. I'm getting error 13213 errors on syncing.
