A DVR is a DVD recorder; it can copy files from one (non-commercial) DVD to another, or from a built-in hard drive to a DVD-R (Recordable DVD) or DVD-RW (rewritable, recordable DVD). Some DVRs can record Blu-Ray disks.
A DVD is the disk itself. It may be a DVD (single density), a DVD-DL (dual density, twice the capacity of a DVD) or a Blu-Ray disk. Commercial DVDs are dual-layer or Blu-Ray.
A DVD player plays the disk on your TV. Blu-ray Players will play any of the 3 disk types mentioned above. A "regular" DVD player cannot play a Blu-Ray disk.
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.
