Well, but the 1990s are over
The time when content was still in tight control of the stations and movie companies is over. Since the change of the century television doesn't work that way any more. Since then it simply became possible to just get your receiver to record everything you could have an interest in in a DRM free format so you can do whatever you want with it.
Those products are trying to use DRM to turn back the clock to the 1990s when making copies was hard and lossy.
