The 'region coding' scheme prevents virtually every commercial DVD from being playable in most regions of the world, raising the prices and reducing the availability of works to legitimate buyers. CSS together with the web of laws and contracts around it also eliminate the individual's ability to make noninfringing copies of DVD images. The restriction is imposed by contracts, implemented by technology, and enforced by DMCA lawsuits. There is no balance. CSS does not follow the boundaries of the copyright law.
Professors are unable to make excerpts to show their classes.
Parents are unable to make VHS copies for their kids' VCRs. Programmers and artists are unable to manipulate the images with their own software. The CSS's blanket prohibition of copies and excerpts throws the baby out with the bath water. CSS prohibits all fair use copying, as well as all illicit copying. It prohibits all copying.
