I don't know if anyone else has had this problem, but when I download a new show from itunes, it replaces the old shows in my video app, and also makes replicas of itself, where other show were.
The old shows aren't deleted from my ipad, as when I search for them they are there, and can be watched that way. But it's a pain to have to do that for every episode of a series.
If I want to download something new, i have to back up my ipad to iCloud, delete the old shows, then download the new ones. Then if I want to watch something from before, I have to do this process again.
I've tried everything I can think of to fix the problem, but nothings working.
