This is what is happening in the US cable market if you are using a
cable-provided DVR. They can allow you to time shift a program that
would otherwise be copy protected on the analog outputs. And they can
control retention time (and, I think, number of views). The cable
DVRs have much higher penetration than standalone units in the US
and most consumers are happy with the arrangement. Units that allow
programs to be recorded to DVD, at the disgression of the cable operator,
are in the pipeline.
Some of the major cable equipment vendors have decided to focus on the
low level bit twiddling (including DRM) and open up the presentation
layers to 3rd parties, so we could see a Cisco/SciAtlanta DVR running
Tivo software in the near future.
