My iPod won't update iTunes with Last Played info. I'm not sure if other info (such as star ratings, play counter, etc...) are updated.

I've got a 30gb, v2.0.1, iTunes 4.0.1, OSX... all the latest.

I assume the iPod works like iTunes in that you have to play the end of the song before it will change the last played date and play counter. But, there are some songs on my pod I know were played completely and they aren't updated. Any ideas?
