DVD copyright protection has been a heated topic for a long time among DVD collectors who attempt to make a backup of movies to protect original DVD from scratch or damage.

So in this article we will specifically show you what's DVD copyright schemes, the legality to remove DRM from DVD, recommended protected DVD ripper and how to strip those encryption off DVD discs and rip copy protected DVD successfully.

DVD Copyright Protection: Detailed DVD Copy Protection Types

The knowledge of DVD copyright measures is just a tip of the iceberg. There are mainly six types of DVD encryptions technologies applied to commercial DVD discs, including Disney New DVD Copy Protection,The Analog Protection System (APS), Commercial DVD CSS encryption, DVD Region Code, User operation prohibition (UOP), and Sony ARccOS DVD protection. Here we will have a look of these DVD copyright schemes in brief.

1. Disney X-project protection

It is probably the most complicated DVD copyright protection schemes used by Disney that even many professional DVD ripper cannot handle. Generally, a Disney protected DVD comes with 99 titles, which makes the removal of DVD copy restriction a hard nut and many software fails to select the right one from the 98 fake titles.

And newer DVDs appear in an oversized way, up to 50GB, making it impossible to make a backup of it. Worse still, the Disney new copy protection scheme may lead to crash halfway when ripping Disney protected DVDs with Handbrake, MakeMKV or other free DVD ripper software. Some programs, though equipped with protected DVD decrypting feature and managing to rip the Disney copy protected DVD, but output videos in disorder or turn out to be out of step.

Representative movies protected with Disney X-project measure include Frozen, Raya and the Last Dragon, Black Widow, Free Guy, The Lion King, etc. Many DVD ripping programs fail to handle Disney DVDs with error messages like "Failed to open disc", "The volume key is unknown for disc", or they output short segments.

2. The Analog Protection System (APS)

APS is another DVD DRM system originally developed by Macrovision, intended to restrict copying or redistributing DVDs. It functions by adding pulses and forcing copies to be degraded or inhibited when copies are made of video signals containing the Macrovision signals. Thus, videos copied from DVDs encoded with APS become garbled and unwatchable.

3. Sony ARccOS DVD protection

Sony ARccOS DVD protection is a copy-restriction system used on most Sony DVDs. The system deliberately creates corrupted sectors on the DVD, which leads DVD copying software to produce errors and most DVD players such as Sony DVPCX995, Toshiba SD4700, etc won't access to the areas (see how to successfully copy DVD with bad sector). But nowadays, many DVD rippers incorporated with DVD copy protection removal, such as MacX DVD Ripper Pro, have been designed to get rid of the DVD copy measures.

4. DVD Region Code

This is achieved by way of region-locked DVD players, which will play back only DVDs encoded to their region. For instance, the DVD sold in the U.S. won't be played on the standard region 2 DVD player purchased in the Europe. However, region-free DVD players, which ignore region coding, are also commercially available, and many DVD players can be modified to be region-free, allowing playback of all discs. New movies on DVDs are encrypted with region code too.

But the advanced region-code enhanced, aka RCE, will prevent the playback of the disc even in a region-free player. But nowadays, many DVD copy protection removal software like DVD Shrink, MacX DVD Ripper Pro can remove region code from DVD and make a backup copy of region-coded DVDs without any problem.

5. Content Scramble System (CSS) Encryption

Content Scramble System, also known as CSS, is perhaps one of the most common encryption systems employed on commercial DVD discs. It capitalizes on a proprietary 40-bit stream cipher algorithm, which was introduced to stop byte-for-byte copies of an MPEG (digital video) stream from being playable.

This DVD encryption measure has been superseded by newer DRM scheme like CPRM that has 56-bit or 128-bit key sizes, providing a much higher level of security than the weak 40-bit key size of CSS. But a number of DVD copy software like Handbrake, if libdvdcss or Decss is installed, has no problem of ripping CSS protected DVD.

6. User operation prohibition (UOP)

User operation prohibition (UOP) is a form of use restriction on DVD discs. The viewers are prohibited from performing a large majority of actions on a DVD that is restricted by this scheme. Generally, copyright notices and FBI warning (in the United States) will be displayed if any of these actions are attempted. Some publishers also encode "protected" (i.e.,"unskippable") commercials on their DVDs.

But many advanced programs can fast-forward or skip the warnings and jump to the main menu to ensure a successful DVD ripping without decrypting errors.

Remove DVD Copyright Protection, Legal or Illegal?

Is it legal to unlock copy encryption from DVD? Or in other words, is it actually lawful to rip copy protected DVDs? Frankly, circumvention of an access control technology is unlawful, so is ripping a DVD with copyright protection, according to 1998 DMCA that stated "No person shall, without the authority of the copyright owner or the law intentionally remove or alter any copyright management information". But this doesn't mean you will be caught for ripping copyright protected DVDs. You still have some wiggle room. As long as you don't share the video files, it's unlikely you'd get caught, unless your hard drives were seized by the authorities.
