The Samsung Media Hub gives you access to TV show titles from Fox, MTV Networks, CBS, Universal, Paramount, and Warner Brothers digital distribution. You also get a whole catalog of movies from all the major studios, literally at your finger tips. Media hub allows you to rent or own the material. If you elect to own it than you can share that content with up to five Media Hub enabled devices.
Through carrier billing you don’t need to tie a credit card into your media hub account, you can elect to pay it via your T-Mobile bill.
