Can anyone successfully make their Padcast/itunes U app in sync with their itunes library? I have been using those two apps to watch videos and such, even though i finish watching some videos, that video file wont be marked as watched on itunes. Additionally, the itunes U videos that I in sync with my ipad ONLY shows up on my videos app, but not my itunes U app. I need to use the app to redownload all the lectures videos. Does anyone have the same question as me?
