Podcast Problems

I a new to the Fuze and find that I really like it.  I am coming from an iPod/iTunes background.  I am finding that when I listen to podcasts, do not finish listening to one before I sync the fuze with my podcatcher to update some of the podcasts, the “bookmark” for the podcast gets reset to the beginning of the podcast.  With the iPod, this “bookmark” was pretty sticky and would be there after syncing.  Is there something I am doing wrong or is there some setting that is not correct?  I am using MediaFly.com for podcatching and syncing.  Any suggestions would be welcome.  Thanks
