Can you record a show from your DVR to a disc on your DVD player your DVD player is not a DVD recorder?

NO Not unless you have a recorder. The laser in a recorder burns the data onto the surface of the DVD. If you wish to transfer a video file from your Digital Video Recorder to a Disc, you must have a burner to do so. You may, however be able to transfer the data from your DVR to your computer using a cable. But not knowing your model, I cannot advise for sure.
