Trouble downloading purchased movies to ipad mini

I just bought a new ipad mini and I can't download purchased movies and music to he mini. When I attempt to download the music and movies from the cloud, the download meter shows progress up to 100% and then stops. When I go to my video section or music section, there are no downloads. I have read a ton of articles and attempted every solution possible. I restored my ipad mini from the ipad. I synced with iTunes and tried to download the music and movies from there. Nothing seems to work. Mysteriously, there are times in iTunes that e video meter shows a lot of space on my ipad being used by videos. Then it goes away and then shows it again later as if he videos are taking up space on the ipad. When connected to iTunes, if I click "on this ipad" then movies it shows the movies listed numerous times (showing I have attempted) over and over. Still there are no movies and no music. Can someone that is an apple expert help me solve this problem? I have tried all that I know. I have even tried to convert the videos to ipad format but that option is grayed out. If I click on a movie and go to the convert options they are all grayed out. I have looked at the content ratings, the resolution,and even a suggestion about surround sound. Nothing works for me. I contacted apple support and the lady was unhelpful and suggested I call for paid support. I do not feel like paying for help on an expensive item that I just purchased and does not seem to work. Help!
