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. 

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.

Cool, but at $2500 each, and only in quantities of 100...

Doesn't looks like this one supports all HD resolutions, and framerates decline
in the higher resolutions.


One reason why they'll be expensive - anytime you grab a signal from a
DVI/HDMI cable or component cables, you're pulling the decoded signal.
You'll have to reencode the signal, and that will require some serious
processing power.
