Thanks for visiting Apple Support Communities.
You may want to try setting up syncing in iTunes again by following the steps in the article below. If you're syncing music, try un-checking and then re-checking the sync videos checkbox in iTunes.

That apparently was not the answer, since I have been synching my iPhone manually for a long time now, and making it automatic did not solve the problem either.
I backed it up, and then restored it from the backup; that seems to have solved the problem.
Thanks for your help anyway!
