Videos not syncing to iPod
I have an iPod Classic 80 GB which is synced to the iTunes Library on my MacBook Pro. Till now, I all the movies that I had added to the iTunes Library had successfully synced to my iPod. Recently, I added 3 movies to the iTunes Library which I wanted to sync to my iPod. These movies are not being synced to the iPod. When I connect my iPod, iTunes says 'Syncing iPod' and after about 3 seconds it says 'iPod syncing complete'.I have not had this problem ever. Also, I know there are third party applications for syncing movies to iPod, but I would not like to use them.
Could somebody please help me with this.
iPod classic, Mac OS X (10.7.1), 80 GB
