iTunes prob

HI for the past week 3 of my recently purchased movies and TV shows have tried to automatically download, once when the TV show was already downloaded.

it then deleted the TV show from my iPad. I have tried to just let them download but they pause halfway though and won't star so I canceled them onl to see they are trying to download again a few hours later. I have tried a reset and a wipe and restore but they are still not working.

CAny any anyone Help?

(sorry about the bad grammar)
