Doesnt work on IPhone

This app is so frustrating. I tried downloading some TV shows that we had recorded to my iPhone so I could watch them on an airline flight. The app told me they had downloaded to my phone but they didnt show up in the downloads. Then we couldnt watch them on the TV later because it said they had been downloaded to my phone. Ugh! So frustrating!
