I was wondering if anyone knows a way to encode/encrypt/lock videos that are copied from a computer onto a Media Card (MicroSD card).

The idea is this: We would like videos copied to a Media card be "locked" to only be viewable from that media card. We don't want the user to be able to easily copy the videos to their computer (e.g. using "Mass Storage Mode") and easily copy them to any other Media Card.

I know that when you enable Encryption mode on the Media card, if you take pictures with the Pearl/Curve camera, you cannot then simply copy those pictures from the Media card to the computer, they are 'encrypted' to just that particular media card.

Any ideas?
