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.
Thanks for letting us know about the issue that you are experiencing.
Is DC Universe the only channel that you observe this issue with? It's possible there may be an issue within the channel itself that the service provider will need to investigate.
Try removing the DC Universe channel from the Roku home screen by navigating to the channel tile, pressing the * key on your remote and choosing 'Remove channel'. Then restart your device from Settings>System>System restart. Once your player starts up again, add the DC Universe channel back once more. Does this clear up the issue you are seeing?
If removing and adding the channel back once more doesn't resolve your issue, I'd recommend reaching out to the channel provider directly to report the issue and request additional support. Many channels on the Roku platform are developed and maintained by the channel provider directly, and they'll be able to best assist. If other channels are working correctly, and you only experience this issue on the DC Universe channel (app), that is likely an indication that the issue lies within that particular channel. In these cases, the channel provider will need to investigate the issue in order to help resolve it.
