If you are looking for a card to capture component video, it doesn't
exist. The cards out there now can capture over the air only because it
is still compressed to it's 19Mb MPEG (max) stream. Once uncompressed,
either in the form of DVI or analog component video, it would need to be
re-MPEG encoded in real time. There are boxes that broadcasters use to do
this and cost 10s of thousands of $$.

Bill,

Thanks for the prompt reply and helpful information.

Just to be sure I understand: the reason you can't input an HDTV
signal from a cable box to a computer graphics card for less than
$10,000 are strictly technical issues and not legal or political
issues.

Is that correct?

Ron

The cable box is only needed for encrypted/scrambled programs. For
unencrypted cable HD, you can use the FusionHDTV3-QAM made by dvico.com and
available from digitalconnection.com and copperbox.com for $199. This card
accepts the cable input directly, without an intervening cable box.
