Depends on the box, appears Dish and DirecTV don't do HDCP, at least not on non-PPV channels.
Apparently, it should work on Bell TV receivers. But who knows if Bell has it set up differently, aside from the asthetics on screen menus and guide.
Also; did a little googling, and Hauppauge seems to be working on a whole new set of capture hardware.
HDMI input (Note: for use with un-encrypted HDMI video sources)
= doesnt say it won't work with HDCP sources either.
