No. Roku uses an Internet connection to deliver movies, TV shows, news, documentaries and more, right to your television. The only requirements are a Roku player, a TV, a high-speed Internet connection, and a Roku account.
The only time you will need a computer is to activate your (free) online account on roku.com or to edit your account details.
