Hey, @drillbit.
Thanks for inquiring!
We understand that you want to turn off the captions on your shows while watching on the Roku App, and we're happy to help!
Let us walk you through the process.
- Launch any movie on your Roku App.
- During playback, tap the screen to bring up the playback controls. In the upper right, there is a text box-looking icon.
- Tap it and change the captions or turn them off in the window.

We hope this helps! Let us know if you have more questions.
Best,
The Roku Community Team
