@Marcus:
I don't want to wake any sleeping dragons here, but (as is widly known) at
least the AV7110 is perfectly able to decrypt without a CAM. It has a full
ECD implementation and one only needs to give it the right keys.
But who am i telling this to, you sure knew this - after all convergence
silently removed the ability to do just that at 31.12.2001 from the driver.
