Hello, @Presidente y Hermana Witt! Welcome to the Zoom Community! We're glad to have you here.
In many cases, this comes down to a screen-sharing setting, so there are a few things you can check before your next event.
Before you begin sharing, make sure you:
- Start the movie on your computer first.
- In Zoom, click Share Screen and select the window playing the movie.
- Turn on Share sound before you begin sharing. Without this enabled, participants won't hear any audio.
- If the movie is playing in full-screen mode, enable Optimize for video clip for smoother video playback.
- If you're expecting around 75 participants, it's also worth running a quick test with a few people ahead of time to confirm that both the audio and video are coming through as expected.
If you can also let us know where the movie is stored, such as Apple TV, Movies Anywhere, or another service, the community may be able to provide more specific guidance. Some services use DRM protection that can affect screen sharing, even for purchased content.
