DVD Rippers are considered 'illegal' in most countries
including the USA. Therefore we can not list or link
to any DVD Rippers. Below is a brief explanation on what
a DVD Ripper would remove:
Restrictions
DVD-Video has four complementary systems
designed to restrict the DVD user in various ways: Macrovision,
Content Scrambling System (CSS), region codes, and disabled
user operations (UOPs).
Macrovision
Discs can specify that the player use Macrovision,
an analog anti-copying mechanism. The video itself is not
Macrovision signaled (unlike Macrovision-enabled VHS tapes);
instead, discs may have an instruction that tells the DVD
player to add the Macrovision signal during playback. Some
DVD players can be configured to disable Macrovision.
Macrovision prevents the consumer from copying
the video onto a VCR tape by using a deliberately-defective
signal which may also cause problems for some projection
TV's as well as older television models. This alone would
not prevent the duplication of DVDs in their entirety without
decrypting the data, given suitable equipment, although "consumer-grade" DVD
writers deny this ability by refusing to duplicate the
tracks on the disc which contain the decryption keys.
Content
Scrambling System
Most DVD-Video titles use Content Scrambling
System (CSS) encryption, which is intended to discourage
people from making perfect digital copies to another
medium or from bypassing the region control mechanism.
The CSS system has caused problems for the
inclusion of DVD players in strictly open source operating
systems, since open source player implementations cannot
officially obtain access to the decryption keys or license
the patents involved in the CSS system. Proprietary software
players may also be difficult to find on some platforms.
However at least one successful effort has been made to
write a decoder by reverse engineering, resulting in DeCSS.
This has led to long-running legal battles and the arrest
of some of those involved in creating or distributing the
DeCSS code, through the use of the U.S. Digital Millennium
Copyright Act, on the grounds that such software could
also be used to facilitate unauthorized copying of the
data on the discs. But as US law stops at the border of
the United States, the rest of the world can enjoy de-scrambling
software to bypass the DVD cartel restrictions.
Region codes
Each DVD-Video disc contains one or more
region codes, denoting the area[s] of the world in which
distribution and playback are intended. The commercial
DVD-Video player specification dictates that a player must
only play discs that contain its region code. In theory,
this allows the motion picture studios to control the various
aspects of a release (including content, date and price)
on a region-by-region basis. In practice, many DVD players
allow playback of any disc, or can be modified to do so.
Entirely independent of encryption, region coding pertains
to regional lockout, which originated in the video game
industry.
