If a recording shows an error or a black screen when played, the file is most likely incomplete. That happens when the recording was made while another stream from the same account was playing and your plan allows only one connection — the provider cuts the second stream.
- Check your plan's connection count with your provider (1 vs 2+).
- On a 1-connection plan: stop playback first, then record — or upgrade the plan for record-while-watching.
- Delete broken recordings from the Recordings screen to free space.
