If HDCP is done as sensibly, this should be impossible without somehow
getting a private key for HDCP.  Pretty fishy if they've done this.

HDCP is supposed to do a handshake, with signatures, to prove to
upstream that downstream is worthy.  It is tricky but well-known how
to avoid man-in-the-middle attacks.  "Worthy" means: part of the
cartel enforcing non-leakage of signals.

I have not looked at the youtube video.  I assume that it requires Adobe 
Flash, something I don't have on my desktop.
