[mythtv-users] capture from hd set top box

[Richard Morton]

just found this, I just wanted to see if anyone had tried something
like this for HD capture.
I know hdcp should make this "impossible" but I think I saw that the
key had been released/hacked, so it should now be possible although to
get the key baked into firmware or software already would be quite
impressive.
