If the recording that has been scheduled has changed or is incorrect, the best to do is to modify the one that you have already scheduled instead of creating a new one.
Here is the detailed procedure:
- Go to the Schedule tab.
- Find the game you want to modify.
- Press Edit on the top right.
- Modify the field(s) you wish to edit.
- Press Save on the top right.
- After a few seconds, you get a confirmation that the scheduling has been adapted.
A recording that has already started cannot be moved or rescheduled anymore (the only aspect that can be changed is the recording end time. This article describes why this is a recommended thing to do).
