Most DVD movies are encrypted with CSS encryption. CSS stands for Content Scrambled System and is in place to prevent the illegal copy of the disc in question. This has become an older security encryption and has been super seeded by the newer AACS, which stands for Advance Access Content Systems. This was developed to be used on commercially published DVDs and blue ray discs. DVDs with any kind of the previously mentioned encryption formats cannot be copied directly to the hard drive of your PC without the aid of software to unscramble them. Software like DVD NEXT COPY will safely backup your movies and maintain a high quality product.
Burning a DVD means you are taking the data files that you have ripped previously and then put them onto a blank CD or DVD using software and hardware on your computer. They are then playable on your PC, or stand alone CD and DVD players. Most good software will do the ripping and burning stages in one complete cycle.
Something to be aware of when burning and ripping DVDs is the region codes. Different countries have different codes and this is to prevent illegal distribution. The US in region 1 and if you are ripping a disc from a different region you are living in then you DVD software should be capable of either eliminating the region function or changing it to the region of choice by applying the appropriate codes.
It is important to understand the difference between dvd9 and dvd5 when ripping DVDs. DVD9 is also known a a dual layer disc and dvd5 is known as a single layered disc. Most movies bought nowadays are dual layered which means they have an additional layer of data and can store up to 8.5gb. The single layered discs can hold up to 4.6gb and are the most used format when it comes to burning because they are the cheapest. There are several different formats of blank media and the most common are DVD-R and DVD+R. These formats both stand for the same thing. Digital Versatile Disc Record but the +R is the newer technology of the two. The draw back is that it wont work on some older DVD players. Most DVD players and burners on your PC will indicate what compatibility they are on the front of the drive. You can also buy the +RW format which is the re-writable version which means you can store data and then erase or over write it at a later date. These are ideal for backing up your PCs data regularly and only having to use one disc. They are not the best for copying movies to because only about two thirds of players read this format.
The different speed at which a DVD is copied will affect the time it takes to do a successful backup. You will need to look at your burners speed, found on the front of the burner or in the manual and the speed of the DVD, found on the DVD box or disc itself. Most software programs will burn at top speed as the default setting but this is not always good as burning at higher speeds results in more errors. If you are experiencing errors then try decreasing the speed to see if it resolves the issue. If you do not have a DVD burner in your PC but maybe only a CD burner than you do have the option of burning onto VCD and SVCD. This stands for video compact disc and super video compact disc. The super version holds more data but both hold a lot less than one average DVD.
After you have ripped the DVD to your computer then you are not limited to backing it up on a disc. You can use the DVD software, if you have a good piece of software, to change the format and use the files on your handheld devices such as iPods. Different formats include AVI, which is a Microsoft technology and stands for Audio Video Interleave. The AVI format produces high quality sound and images and is a great choice if watching the files from a PC. They are also relativity small compared to the DVDs raw files and make it good for sharing. Another format is DIVX and XVID. Both of these are forms of the AVI format but sometimes you are required to download a codec to view them. A codec is a package available for free on the web that once installed will tell your PC how to read the files to make them viewable. Mpeg4 files give high definition images and is the format Apple use on their iPods. Apple computers use mainly the .mov or .m4v formats which were developed by Apple and are used for apps like Quicktime and iTunes. They also deliver a high quality image.
