The DVR log is split into a series of paged grids:

Use the bottom toolbar (not displayed in this manual) to navigate between pages in the grid.

To see more details about a recorded event, just click on it and a pop up will appear:

In this pop up you can cancel a scheduled recording or abort a recording in progress. To close the pop up, just close it with the [X] window button.

Once the recording is completed there will be a clickable link to the recorded matroska file so you can download it directly from the interface.
