Yes if the DVR also has a DVD burner in it or is a DVD burner.
Stand alone DVRs come in two basic types one uses a DVD-RAM to provide the PVR function. The other has DVD burner and a Hard Drive for the PVR function.
The second type is more veirsital but cost more.
Both have RF and AV inputs.
Some are a combo VHS/DVD/PVR. John
