This will most likely be your last achievement for this app. It requires you to watch approximately 16.66 hours worth of video content without fast-forwarding. This means your app needs to run for that entire time, but you can have the app snapped to enable you to do something else whilst allowing the TV episodes to run. Once you have all of the clips, your first episode, and content from three TV shows done you will need to grind out "Voracious Viewer" (15 episodes), and in doing so put yourself right at the cusp of 1,000 minutes of content.
What I suggest is Girlfriends Guide to Divorce and scrolling to the right until you get to Season 1, Episode 1 which is one of the longest episodes on the app. Allow it to run, finish, reload, and repeat.
