Hi @JLill,
Thanks for reaching out here in the Roku Community!
We're sorry to hear about the playback issue with the channel. Have you tried following the troubleshooting steps on our support page to see if they helped resolve the issue? How to resolve a channel playback issue
If you are still unable to play videos from one channel after attempting the suggestions on the link, videos from other channels play fine. Contact the channel provider's customer support team to report the issue and get help. Channels on Roku are maintained by the channel developers themselves. In this case, there's likely an issue within that specific channel that needs to be addressed with an update from the channel developer.
All the best,
Chel
