From the viewpoint of copyright protection, digital broadcasting (terrestrial, BS, CS) is a video with a limited number of recordings, which is “recordable only once” in principle.
To record this video on a DVD, the conditions are
(1) the disc is CPRM compatible, and
(2) the disc is formatted in VR mode
Also, only DVDs supported by the device can be recorded. Therefore, depending on the DVD recorder, if the model cannot use the CPRM compatible DVD-R, or if the model cannot format the DVD-RW in VR mode, digital broadcasting cannot be recorded on that DVD. Regarding this point, please check the DVD that can record digital broadcasts in the instruction manual of the DVD recorder.
