Most DVD movies have copy protection which means normal dvd burner software can't make bakup copies of your
dvd movies.
Here at Best-DVD-to-iPod-Software-Reviews.com, we've researched and found the best
dvd to ipod software available and most of these products can copy CSS copy protected DVD movies and many fairly current
releases which employ Sony DADC ARccOS protection. The best 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 to ipod conversion 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 the best DVD to iPod 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 or convert 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 or DVD to iPod conversion
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.
DVD makers can, however, author a DVD (the
process of writing the original DVD) in such a way as to make it difficult to
copy or convert if you exploit weaknesses in the design of DVD conversion software. A great deal
of effort has been spent on trying to make new DVD movies difficult to copy or convert, but
still play 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 to your ipod which incorporates one of these authoring techniques,
it may fail during the conversion 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 to iPod application like 1CLICK DVD To iPod which
incorporates CPRx error correction technology.
11/28/2007: CPRx error correction technology -
Important! This technology is only available with
1Click DVD to iPod.
<-- This is what you should buy. This software can copy the most
protected DVD movies and is constantly being updated (every few weeks).
The 1Click products from LG Software Innovations
now sets them apart from other DVD copy software in the industry. Each week more and more DVD movies
will be released that can ONLY be copied with the latest version of
1Click DVD to iPod. They offer frequent updtates (every week or two).
This technology permits their software to copy virtually every DVD in
circulation. Their intention is to continue to provide frequent
updates going forward to ensure they can retain this capability.
CPRx technology is an innovative
solution for copying new DVD movies which have bad sectors or bad DVD structure.
Users of the 1Click software have access to frequent updates via internet download to
