FireTV App -- 2

I need a FireTV app to play fitness videos from my video CDN. The app needs to allow searching and show videos by category, by instructor, watched videos, and favorites. The user will be able to navigate the available videos, select a video to see additional information about the video, see whether they have watched a video, save a video as a favorite. The video will play in full screen with the ability to pause, play, fast forward and rewind. Authentication will be required similar to existing apps and I will be supplying the web API for the content. One thing to note is the videos are only authorized to play from my domain so that will need to be accounted for. Also, there are over 500 videos so infinite scrolling will be needed. A professional looking application is required and I will supply all images and logos.
