That you can copy everything you can see is correct of course...
But that doesn't necessarily mean that you can make digital copies of it, and that is the problem...
One approach of making copying unattractive is to "close the analogue hole", you can not even copy to VHS then.

Maybe THEY will in a not so far future only build and support standalone players with IEEE.1394 (firewire) output, that is heavily encrypted, only works for one TV (includes some authentification mechanism like PGP or something) and so on...
You can of course copy that by filming it from your TV, but the quality will suck of course.
And the real problem is, that they only have to include the most simple form of copy protection, and you are not allowed to investigate into, build, talk about, think about, hear about or tell anyone about tools that could eventually break this protection in europe and in the USA.
Of course there will be gifted and dedicated people who will find a way to make digital copying possible, but it probably will be very hard, and take much longer than breaking CSS did (they probably won't allow software DVD players for the next format, and when, only with authentification over the internet).

And the thing about digital watermarking is not that they can find out who made the copy, but if they search one's house for whatever reason they make up, and find a DVD which has a few copies distributed around the net, this person is really f*cked...
