1. You can initiate a forced update at any time by restarting your DVR (push red reset button behind front panel access card door), then use your remote to enter 0 2 4 6 8 when the first startup display appears. However, you might just reinstall your current software unless a new software update has been distributed for your DVR. And if that's happened, you'll get the update that evening anyway.
