The reason I say it was a great idea, it was a solution to the piracy issue. Now it did not eliminate piracy completely, but made it harder, as MOST will have an HDMI cable and digital connection, and that's mainly what it stops. The way they went about it was just absolutely terrible though. Your source has a long code, and each device connected has to randomly match that long code. Stupid. Definitely needs improvement and a true universal support.
