Hi @jocrase,
Welcome to the Roku Community!
We understand you want to know how to record on Roku when watching a program. We're happy to help. Please be advised that Roku streaming player or Roku TV provides you access to stream movies and TV shows over the internet but does not have built-in storage for downloading or recording directly to the device. However, if their streaming channel offers a cloud DVR feature, you can schedule and store recordings in a content provider’s online storage center. Some channels that offer this feature with a paid subscription include Sling TV, Hulu with Live TV, YouTube TV, FuboTV Premiere, and Philo. You can check this link here for more details.
If you have any more questions or issues, please do not hesitate to get in touch with us or bring them up in the Community. We would be happy to assist you.
All the best,
Eunice
