The MPAA doesnt get it, but the pr0n companies do

The MPAA is not yet ready to allow you to download a movie and burn it yourself. However Vivid Entertainment is.

Porn industry to offer downloads to DVDs

And once again the MPAA and its brethren will certainly eventually catch on, being drug kicking and screaming to the money trough, but do not come up with this on their own accord. (They are too busy with that great CSS stuff and lobbying to get laws such as the DMCA in place - really great for their customers.) Note that the linked CNN article says the porn industry ALSO started the home video market itself (thats news to me, I am not sure whether or not it is accurate, but it sure is not surprising given the brilliance of the MPAA).
