Users of UltraViolet have never been thrilled with the Fire TV’s support for the cloud-based digital rights locker for movies and TV shows. Ever since the launch of the first Fire TV in April 2014, the Flixster app had always been the only way to watch UltraViolet content using a Fire TV. Even then, it was a bad experience due to its slow interface and numerous login issues. Once you finally managed to view your UltraViolet library, it only streamed in standard definition. The Flixster app has now dropped UltraViolet support on the Fire TV, as well as Fire tablets, all together.
Earlier this year, Flixster removed UltraViolet playback from their main apps on Android and iOS in order to release ‘Flixster Video’ apps which were dedicated apps for UltraViolet playback. It’s plausible we’ll see a Flixster Video app released for the Fire TV in the future, but for the time being, there is now no way to play UltraViolet video content through the Fire TV.
