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.
Are you inside the Roku Channel/app or another Channel/app? If inside the Roku Channel, you have to navigate to the Continue Watching section and then highlight the selection (show or movie tile) first before pressing * button. If you look at top of screen to the right, you should see Roku | Options * become available (change color/brighten) whenever the * button can be used.
If you are not inside the Roku Channel, there may be (and likely is) a different way. Different Channels, different methods. Post back with Channel and someone should be able to help.
