Introduction of DVD decrypter For MAC


Backing up DVDs

Encryption/protection

Commercial DVDs that use encryption use a scheme called CSS (Content Scrambling System), which makes them impossible to copy using applications like Disk Utility or Toast.
Of course, the DVD Player application that comes with Mac OS X does know how to decrypt your DVDs - otherwise you wouldn't be able to watch those movies on your Mac!

Protection of DVDs is used in combination with encryption to make it difficult to copy the DVD.

Breaking encryption/protection
To decrypt encrypted DVDs and to break the RCE/structure protection, get the newest version of Wondershare DVD Ripper for Mac, iSkysoft DVD Ripper for mac or DVD Ripper for Mac to extract the DVD to your hard disk. Note that it is illegal to break such encryption in the USA (due to the DMCA) and in Europe.

Disk size
Many commercial DVDs are actually dual layer DVDs that can hold up to 8.5GB of data. As of this writing (November 2005), although dual layer DVD writers are available for upwards, dual layer DVD media still cost a lot (compare around + for one dual layer disc vs. around 30 cents for a single layer disc). So if you want to make a backup of that dual layer DVD without having to use expensive dual layer media, then you need to "shrink" the data on the dual layer DVD so that it can fit on a single layer disc (that can hold up to 4.7GB). On the Mac, you can use commercial applications like Wondershare DVD Copy for Mac and DVD Copy for Mac or DVD2OneX to do this. If you have access to a Windows PC, you can use DVDShrink to do the same. Note that shrinking DVDs means losing out, to some extent, on the quality of the picture and sound. Use one of these applications to create a DVD folder that's smaller than 4.7GB. The application you use would be able to provide you the right compression level to make the contents fit on a single layer disc.

Burning the disc
Once you have compressed the DVD you can burn it using either the free Disk Utility that came with your Mac, Toast, Wondershare DVD Copy for Mac or DVD Copy for Mac (Note that DVD Copy includes functions of DVD burner in the latest version). You can also use Toast or DVD Copy for Mac to copy a single layer DVD or to burn a DVD from a folder on the hard disk, This makes burning DVDs simple, although the application is not free.

Copying DVDs onto your hard drive
If you don't want to have an exact copy of your DVD on another DVD but rather take it with you on your HD, while you travel for example, then just stop after ripping the DVD to your hard disk with  DVD Ripper for Mac. This though will result in a fairly big file, depending on the DVD. If you want to get smaller files and don't care too much about the quality, then rip your DVDs to your hard drive using Wondershare Video Converter for Mac or Video Converter for Mac which will reduce the files to something around a gigabyte depending on the options and the movie.

Copying DVDs to your iPod, iPhone and other Players
If you want to copy your DVD to your iPod, iPhone and other Players, then watch them on your players. You can use DVD to iPod Converter for Mac, DVD to iPhone Converter for Mac or DVD to MP4 Converter for Mac. Set parameters to what you want. These applications will make it easy.
