When the disc is inserted into a player or computer, a series of 'authentication' handshake key exchanges occur between the DVD drive and the player software. CSS utilizes a proprietary 40-bit cipher that is used to encrypt the data stored on the DVD disc.

Rovi Corporation, Content Protection (Wikipedia)ĬSS is an encryption system that is the main copy protection scheme used on pre-recorded DVD discs.

Macrovision Corporation renamed itself Rovi and now promotes other copy protection technologies. With the demise of analog video and the widespread availability of digital decryption tools, Macrovision protection has largely become irrelevant.

Macrovision can be defeated by passing the composite video signal through a hardware device that restores the proper video signal levels. By manipulating the signal level of the composite video, Macrovision fools the automatic gain control of most video recorders resulting in annoying shifts in color and brightness in the recorded video. The Analog Protection System, popularly known as Macrovision after the company that developed it, is a protection system that is applied to the composite analog video signal coming out of DVD players. We will go over each of these schemes in turn. Recordable DVD discs are also sometimes copy protected using Content Protection for Recordable Media (CPRM) encryption. These are Analog Protection System (APS) scrambling, Content Scramble System (CSS) encryption, and a system involving corrupted disc structure. There are three types of copy protection that are used on commercial pre-recorded DVD discs. The purpose of this document is to clarify both the technical and the legal aspects of copy protection for DVD and Blu-ray discs. There is, however, a great deal of confusion about how these copy protection schemes work and what kind of legal rights consumers may have.

The ultimate solution is a TBC however this is $$$ and bit of overkill unless you have other errors like timing issues.Introduction to DVD and Blu-ray Copy ProtectionĬommercial pre-recorded DVD and Blu-ray discs are typically protected with some form of copy protection. Results are hit and miss with these and because of the way they work can degrade the video. (note I'm out of the loop here so I don't know if this is true of the newer ones) or you can purchase something that goes between the VCR and the recording device usually called something like 'video enhancer'. The solution for home video is either buy a device that doesn't look for this signal like the Hauppage line of computer capture devices. Some electronic devices are more prone than others. These errors can be incorrectly flagged as being copy protection preventing recording them.

home movies are full of errors especially when played a lot, stored improperly etc. It wouldn't effect DVD recorders or other electronic devices EXCEPT the manufacturers of most of these devices have bent to the wishes of the media conglomerates and will look for this error and prevent recording if present. Macrovsion and the media companies were able to get this limitation mandated into law so newer ones still have it.

This is an error that is purposely placed in the video, and they patented it! This error does not effect playback on TV but will play havoc with VCR recordings. The protection is commonly referred to as Macrovision but that is actually the name of the company. You enter a gray area with VHS because the protection scheme relies on the limitations of early VCR's. Producing the copy is not illegal, it's the act of circumventing protection schemes where it becomes illegal. As long as she doesn't try to sell the copies. I thought as long as you do it for your own personal use it is not illegal.
