Podcast play count reset when syncing multiple devices

I have noticed some odd behavior since upgrading iTunes to version 10. My wife and I each have an iPhone, iPad, and an iPod nano. I have several playlists that I sync to each of my devices. The problem comes when I play some podcasts on one device, and other podcasts on another device. I sync one device, the play count updates. I sync one of the other devices, and the play count updates on some songs, but is deleted on others. I can tell which tracks have been reset because they still have a Last Played Date. It appears that the device with the most advanced time overwrites the play count in the library.

Anyone have any ideas on how to fix this behavior?
