I'm iTunes free and just use a standalone iPad so I'm not honestly sure. I remember in iTunes (on my Old iPhone) there was a video tab which allows you to see the videos being synced. If i remember i had to select the device (when plugged in) on the left hand side, then i could access what was being synced. Sorry im going from memory and I've not had to use iTunes in a long while so my little tutorial may have changed in recent iTunes versions, someone else should be able to help further with it hopefully. but have a play around. Hope I help you get a little nearer to a resolution.
