Why do all of your questions start with "Why hasn't anyone done 'x'
yet?"  "X" is not done because this is a unpaid volunteer project with
thousands of users and about a dozen people actually doing any work.
We seem to have a surplus of "idea men" though...

It wouldn't.  Closed captioning exists in both the program and
commercials, there would be no way for this to work without teaching
the commflagger the difference between the plot of the show and a
Cham-wow commercial.

You are still misunderstanding what HDCP is.  HDCP is a copy
protection method for DVI and HDMI *only* which prevents the signal
from being displayed at all without two compliant devices.  Since no
capture device in linux directly captures either of these inputs, it's
a non issue.  As explained to you a couple of times in the other
thread, the HDFury is a way of working around this, by stripping HDCP
out and converting to Component, which is capturable with the
Hauppauge HD-PVR.

HDCP *cannot and does not* have anything to do with
reduce/downscaling/resizing/cross-sizing/etc.  The ICT is part of the
blu ray standard, NOT anything to do with cable or broadcast media.
the cable companies would love to (and have lobbied for) implement a
similar standard but have not been permitted to do so thus far.  When
they do, it *still* won't be an issue as the HDFury will work to
bypass HDCP and convert to an HD, captureable output.
