Your Roku® streaming player or Roku TV™ provides you with access to stream video and music from the internet and does not download or record movies and TV shows. However, you can use the Roku Media Player channel to play your own personal movie and music files that may be stored on your computer or USB drive.
Roku Channel Store
Just like your smartphone has an “app store” for installing new applications, you can access the Roku Channel Store on your Roku streaming device to add new “channels”. Channels are applications for your television; popular channels include Netflix, The Roku Channel, Amazon Instant Video, VUDU, HBO GO, Hulu and YouTube. Although some channels must be purchased or require a paid subscription, many others allow you to watch movies and TV shows for free.
When you want to add a channel, theme, screensaver, game or other app, learn how to use the Roku Channel Store to access your favorite movies and TV shows.
