How do you download from a dvr to a DVD?

You cannot download a file inside the DVR unit onto a DVD disk the same way you can download a music file from the iTune store. But you can record output from the DVR to a DVD disk using either a stand-alone DVD disk recorder or computer's DVD writer. Connect an analog output on the DVR (such as S-video, component, or composite for video and RCA / red and white audio) to the input sockets of your stand-alone DVD recorder. Or buy a USB or PCI 'video capture' device for your computer so that you can connect DVR's analog output to the video capture device on your computer. While a TV show is played on the DVR, the stand-alone DVD recorder or computer will record it.
