Download playback is sketchy – EPIX Stream with TV Package Review

On an iPhone 6 (iOS 9.0.2), download playback sometimes doesn't work. I frequently get an error message "Cannot Parse. This data is damaged, incomplete, or incompatible." After a lot of trial and error, I have discovered that this error only happens when I have no wifi and my cellular data connection is weak (1 or 2 bars). When I turn off cellular data altogether, download playback works fine. Epix has foolishly designed the app to require communication with the server when a downloaded asset is played back (when there's a data connection). Defeats the purpose of downloading in the first place! In addition, they play an "Epix" intro clip at the beginning of every asset that is recorded at a much higher volume than the movie/program. It's startling, particularly if you're wearing headphones.
