Another good example of a company pandering to the industry that is taking away our freedom is the DVR market. The C[[aptive Works CW-100R]] would otherwise be a nice, low cost consumer DVR except, although there is no actual use for an AGC circuit, purposely has means to detect Macrovision and block your ability to record the video source.Another good example of a company pandering to the industry that is taking away our freedom is the DVR market.

TiVo is a big offender in placating an industry set out to restrict our freedom. TiVo DVR, also recognize and support Macrovision’s copy protection schemes. The copy protection schemes are deployed by the content/program providers and are limited to specific programs like Pay-per-View, Video on demand or DVD/VHS sources. TiVo responds to the Macrovision’s following Copy protection rules that dictate how long the video may be saved on the TiVo drive, or outright refusing to record the program.== VHS & DVD Protection ==The protection is achieved by implanting physical synchronization vertical signals directly onto VHS tapes. But in case the signal is not physically stored on DVDs rather DVDs are associated with instructions that tell DVD players to create and impose such signals and cause hindrance in recording. These DVD players contain a special chip licensed by Macrovision. In some jurisdictions inclusion of the chip is required by the government, a sign of the success of Sony, Time Warner, and the MPAA in using the government as a tool.== Protection against Macrovision ==Since DVDs are not encoded physically by the signals so it is quite easy to get rid of macrovision scheme by just configuring the DVD player to not to bother about the instructions associated with macrovision. Moreover for video or VHS there are devices available as video stabilizers or enhancers that disables the macrovision spikes by detecting the encoded signals (vertical synchronization signals) and leveling them back to the original level. In February 2005 Macrovision introduced a new protection technology named as Rip-Guard and claimed that 97% of DVD rippers will fail to disable this technology.=== DVD Player ===A standard DVD player contains a special Macrovision-enabled digital-analog conver chip that is activated when a DVD is played. The activated chip applies copy protection to the analog output and causes copies made on most VCRs to be substantially degraded.When you go to purchase a new DVD player try to find one that doesn't support Macrovision. This may not be easy as the vast majority of DVD players do. Models for sale in the United States are required to include a Macrovision chip. Macrovision is a litigation happy company that likes to use lawsuits to force DVD manufacturers into purchasing Macrovision technology and including it in their DVD players.Some DVD players have hacks available to them that will disable Macrovision, much like the region code hacks for DVD players. There are certain code words used to advertise DVD players that have been modified to defeat Macrovision, such terms are: Black Magic,Bullet Proof, and Recorder Friendly. You will see those terms used on auction sites such as eBay as to avoid being delisted. Updating the firmware with a aftermarket / hacked firmware is how it is done.* Apex's AD-600A - can disable macrovision through a hidden menu (not all units had the menu)* Apex 1500 - macrovision disabled through aftermarket firmware upgrade* Panasonic DMR-E20 - ?* WINTAL PDVD2025 - PAL only* Mustek DVD - ? old model ?* [http://checkhere22.com/stabilizer/ Digital Video Stabilizer Model 200]* [http://checkhere22.com/stabilizer/ Digital Video Stabilizer Model 200] - ?* Sima SCC Video Color Corrector* Sima SCC Video Color Corrector - works okay for most VHS, but not all, and doesn't remove CGMS/a.* [http://www.mcmelectronics.com/product/80-4280 MCM Digital Video Stabilizer] - doesn't remove CGMS/a.* [http://www.stardevelopment.com/videomagicdvd.htm Video Magic/ULTRA Video Clarifier] - reported to remove CGMS/a.The ADS IDVD will also ignore Macrovision.The ADS iDVD also called the [[ADS Instant DVD]] will completely ignore Macrovision. This little box cheerfully encodes any video source without regards to whatever pathetic analog copy protection is present. The ADS Technologies Instant DVD (iDVD) truly takes advantage of the analog hole. == Resources == * [http://www.cameratim.com/reviews/movies/macrovision Macrovision is an abomination] == Related Topics == * [[Cinavia]] - analog audio watermark that embeds a human undetectable waveform in the audio hearing frequency range of the media.
