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

Use the bottom toolbar to navigate between pages in the grid.

Note that the columns are sortable, but only the current view will be sorted (by default, this will be the first page of the most recent events). Select more events per page if you want to sort a longer selection.

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.
