iPad won't sync movie or tv-shows

Hi to you all, and especially to all you Apple people.

I recently upgraded my iPad2 to IOS6.

Everything went fine, and I have had no problems so far.

Untill yesterday when I wanted to sync some Movies and TV Shows through iTunes (10.7 (21)).

No matter what I trie or do, neither of those files get synced with my iPad. And there is plenty of room on the iPad to store them.

Before iOS6 I have never had any problem with this feature whatsoever, so I really want to know what has changed in iOS6 that prevents me from syncing Movies and TV-Shows.

Oh, and before anyone gets 'smart'; the files I want to sync are correctly labeled TV-Show or Movie (the Info-Options tab in iTunes where you can set Media Kind).
