Help with Movies and Ipod Nano

Yes. Movies you purchase from the iTunes Store can be synced to your 7th generation iPod nano.

I have to disagree, for some reason 1 out 5 movies i have purchased through itunes have been able to be uploaded to our Ipod Nano. Don't understand why, have tried to file convert through choose file, create new version, but that option won't highlight. Still looking for help
