Welcome to the Roku Community, @cliffh!
Thanks for reaching out. We'd be more than happy to help you find a workaround for showing the videos and music on your computer on your Roku TV.
We highly suggest using the screen mirroring feature. Replicate or mirror the screen of your phone, tablet, or computer onto your TV screen. Display web pages, videos, photos, music, and more on your Roku® streaming device.
Kindly follow the steps provided by our support article here: How to screen mirror from your phone, tablet, or computer to your Roku streaming device
Feel free to reach out if you need further assistance and clarification. We're here to help.
Best regards,
Carly
