Itunes won't download videos onto my iPhone 5s?

I have the latest version of IOS 8 and latest iTunes update. Whenver I go to download videos onto my 5s it won't download. I click "On my iPhone" when syncing and the videos have grey dotted circles around them. It says that it downloads all content onto my phone but when it finishes up downloading it hasn't even started downloading the videos. I've tried to uncheck the videos, sync, recheck, sync but that doesn't work. The songs and apps are fine - they sync properly but not my movies, tv shows, or home videos.

I never sync my phone or iPod for music or video - I just do manual management of music and video, then drag and drop the songs or videos onto the iPhone tab on sidebar. Sometimes the song or movie stays grayed out. That happens when iTunes gets updated, but before I reboot my computer. You're supposed to reboot your computer after an upgrade.

If you have problem with iTunes, and it does not download videos onto my iPhone 5s, you may use iPhone/computer transfer software to transfer Apps, Contacts, Songs, Videos, Photos, Playlist, Games, etc between iphone and computer.
