There's nothing in law preventing someone from making a computer card
that accepts input from component, DVI, or HDMI, and compressing it to
what is practical to transfer over the PCI bus and store on disk. The
content industry would like such a law, but they have not gotten it.
But it really isn't that much of an issue for them since virtually all
HD programming will either be already compressed in the clear (e.g. OTA)
or will be capable of being DRM restricted (e.g. whatever-DVDs) so that
an HDCP compliant player will refuse to play in HD if the display unit
attached is not also HDCP compliant.

What is probably preventing such cards entering the consumer market is
the lack of market. Few people have any other HD content to be recorded
that would need these kinds of cards. Professional video producers and
broadcasters form a different "pro" market where stuff costs a lot. So
the content producers really won't have the much to worry about in this.
Maybe the internet will keep them busy.
