Most DVD movies have copy protection which means normal dvd burner software can't make bakup copies of your dvd movies.

ConsumerFirstReviews.com has done the research and found the best dvd copy software available. Most of these products can copy CSS copy protected DVD movies and many fairly current releases which employ Sony DADC ARccOS protection. The highest rated of these DVD copy programs can and will be able to copy all DVDs including the latest, and future DVD releases. Please see the section on CPRx error correction technology below. Only a year ago, most DVD copy programs listed on this site could copy almost any DVD. These days, the movie industry has taken increased steps to prevent you from making backup copies of your DVDs. This is why it's very important to buy software that includes the latest CPRx technology.

Content Scrambling System (CSS) - Almost all DVDs are encoded with CSS, which is a digital encryption scheme. DVD players can play DVDs encrypted with CSS because they each have a key to unlock the information on the DVD. Another way to think of CSS is a locked door. DVD players can unlock the door. Similarly, a software decrypting program can unlock the DVD and permit to a DVD copy application.

Macrovision - Many DVDs contain Macrovision, an analog copy protection. When a DVD player plays a DVD encoded with Macrovision, the DVD player will output a video signal which is incompatible with analog recording devices, such as VHS tape recorders. Macrovision is not a digital protection, so it has no effect on software which is designed to copy a DVD.

3rd Party Decrypters - Most mainstream DVD copy applications depend on third party decrypting applications to remove CSS and Macrovision from the DVD. The removal could be done on the fly (while copying takes place) by tools like DVD43 or AnyDVD, or as a separate process which rips the DVD contents to a hard drive folder (using tools like DVD Decrypter) prior to the DVD being copied. Both CSS and Macrovision are static entities which cannot change. If they could change, hundreds of millions of DVD players would not know how to play the modified DVDs. So this brings up a couple of interesting questions.

Why do a lot of new DVD releases now claim to be “Copy Protected”? and   What is this new copy protection and how does it affect a DVD copy application?

The fact is there are no new “copy protections”. To create a new copy protection, you would also have to change the way a DVD player works. DVD players must all conform to rigid specifications to ensure proper playback. A new copy protection cannot be introduced unless the DVD player specification changes.

You can however author a DVD (the process of writing the original DVD) in such a way as to make it difficult to copy if you exploit weaknesses in the design of DVD copy software. A great deal of effort has been spent on trying to make new DVD movies difficult to copy, but still playable on a DVD player. Some simple examples are the inclusion of bad sectors (defects analogous to scratches) or bad DVD structure (adding bogus content to a DVD) which are blatant attempts to inhibit archival programs from making backup copies of the DVD.

Sony Arccos, Macovision, Rip Guard, Settec Alpha-DVD, and Augs Puppet Lock protection - These are just clever marketing names assigned to many of these novel authoring techniques. None of these authoring techniques constitute real copy protection, simply because the DVD player is totally unaware of their existence and as such, they are only annoyances to DVD copy applications. If you attempt to copy a DVD which incorporates one of these authoring techniques, it may fail during the copy process (often due to bad sectors on the disc) or it may fail to play back correctly because of bad DVD authoring on the original. One solution is to use a DVD copy application like 1Click DVD Copy which incorporates CPRx error correction technology.
