Playback broken with update – DS video Review

I have the exact same problem as ajwhitney. Videos that previously played no longer work (iOS9 and iOS10). Downloaded movies play, but streaming movies or trying to download new movies does not work. These are pretty vanilla mp4's that I'm trying to play. Whole collection is down. Please fix! @scottconnor on Twitter if you need help reproducing.
