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.
How are you subscribe to UKTV? Is your subscription through Roku, or is it through the channel provider directly?
For more information about that channel's features and functionality, you'll want to contact UKTV support directly to inquire further. Many channels on Roku are developed and maintained by the channel provider themselves.
