This app is not consistent

The app does not sync correctly with my cable box. I got X1 so I can watch shows on the go as advertised but I cannot do that if the shows will not download or have "playback issue errors." Sometimes it works sometimes it does not and I do not like that inconsistency...especially when you expect my bill payment to be consistent.
