Somewhat related...I know that people should pay to acquire media. But the way I understand fair use from a layperson's perspective, once you own the media in question, you can convert it to any other medium. One example is a CD to an .mp3 to load on your .mp3 player. However, I know a person who bought a Blu-Ray (TM) and tried to rip a copy to play on his computer but a code blocked it. Does this violate fair-use?

I like how many movie suppliers are now providing a digital copy of movies in the Blu-Ray (TM) sets.
