iPod Recently played tracks syncing problem

I noticed the last couple of times I've synced my iPod with iTunes it's only syncing the last 3-4 hours of listens, nothing previous for that day.

For instance, if I listen all day at work, 9 to 5pm, come home and sync and look at my recently played smart playlist (which I have set to 200 songs) it shows the songs played from 1:00 pm - 5:00 pm, but then all the previous plays from from 9:00 am to 1pm are mysteriously missing - it then jumps to plays from the previous day in the listing.

Anyone else have this problem?

Ah nevermind... I sorted it.
