This is rather a hot potato at the present time. Some providers are
threatening to boycott the format if they cannot protect their content. It
is worth remebering that the DAT audio format was scuppered almost entirely
due to the providers refusing to produce anything for the media entirely
because of copying issues.

The hardware providers on the other hand are aware of the consumer dislike
of copy protection systems (which in several countries (not UK) prevent them
from doing what they are perfectly legally entitled to do).

The position is analogous to the 'no copy' flag on audio CD's (I'll bet you
didn't know there was one). The current audio CD specification prohibits it
from being set (but digital recorders (via digitial input) are obliged to
honour it). When CDs were first deployed, it was not regarded as a problem
because there were no digital recording systems in the consumer market
place. The departure from the CD spec with the introduction of DRM
protected disks has completely sidestepped the issue (and the availability
of DRM removal software has sidestepped the DRM).

Subsequent digital systems (MD and DCC) both implemented copyright
management in the form of SCMS (Serial Copyright Management System), but the
publishers still didn't like it because it allowed a second generation copy
to be made (though blocked subsequent generations).

That jury doesn't look like coming back anytime soon.
