Help & troubleshooting for channels on your Roku device, including adding/removing channels, logging in to, authenticating, or activating a channel, channel-specific playback issues, assistance contacting channel publishers to report issues, and adjusting channel-specific settings.
1) Is your tv successfully connected to the internet? This is needed to stream anything. 2) Do you have a paid established account with Netflix? Vudu doesn't require a subscription but what you can stream for free (with ads) is limited.
