If the MPAA has there way in a recent court filing it will be illegal for you to rip a DVD to put on a portable media player. Instead they will want you to pay full retail for the rights to do that.
The MPAA and there associated members need to come to grips with the new way media is being consumed and get their act together and allow people to pay for media one time and then give them access to all formats. Thus if I buy a DVD within that DVD should be access to a website that would allow me to download the same media for all of my various media players.
But seeing it will be a cold day in hell before they do that, then they must understand that consumers will continue to invoke their fair use rights and copy the media that they own. [EFF]
