The DVI output by most HDTV sources is copy protected. It isn't
encrypted, per se, but the reciever and monitor go through an
authentication dance before the reciever will send a signal to the
monitor. By monitor, I mean DVI-HDCP (or HDMI it's the same
thing) capable TV. One side effect of this is that most
computer monitors with DVI inputs will not work with an HDTV
cable/satelitte box with a DVI output. <br>
<br>
In summary, there is no way to capture the digital output of an HDTV
decorder box with running afoul of the IP police state, and capturing
an analog TV signal presents significant technological hurdles. <br><br><div><span class="gmail_quote">On 11/11/05, <b class="gmail_sendername">James C. Dastrup</b> <<a href="mailto:jc@dastrup.com">jc@dastrup.com</a>
