This depends on the particular model. Some DVRs have DVD players built in, and some do not.
By itself, a standalone DVR (Digital Video Recorder) without a DVD drive built in cannot play a DVD.
You can connect the output of your DVR in a DVD recorder, such as the Samsung DVD-VR375. This will record your DVR programs directly to DVD.
If your DVR has a built in DVD player, yes.
The Toshiba SD H400 - DVD player / DVR is a good one.
Run component cables (red,whit and yellow) from the DVR "video out" (yellow) to the "video in" of the DVD recorder. That will send the picture to the DVD recorder. If your DVR or DVD recorder does not have the yellow video out or in as described, use the "S video" out of the DVR to the "S video" in of the DVD recorder. The red and white jacks are for sound....out of the DVR to the audio in of the DVD recorder.
There are several DVD recorders that come with DVR capability
Yes, you can do this. You hook up your DVD recorder up directly to the DVR.

Some of them.
Transfer Recorded Show From DVR to DVD, Most likely not, until you connect the output of the DVR to the input of the DVD. Then with copy protections, you may still not get a recording. Depends on the movie or program you recorded, and whether or not copy prevention signals have been inserted in the original program, or are being placed there by the program provider.
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.
Any DVD/VCR combo with a composite out will work great with your TWC DVR.
