Emby (formally known as Media Browser) is a powerful media server system with apps available for a wide range of platforms. The Windows Store version which supports Windows 10 and Xbox One has been recently been updated adding one of the most requested features – Live TV seeking. With the new version you can pause, rewind and fast forward live TV from the app. You need an Emby Server configured for live TV for it to work and server is available from Emby.Media for free.
The app is designed for the 10 foot lean back experience but also works really well with mouse and touch.
You can find the updated app in the Windows Store.
