DVD Copying Terms Explained

There may have been a time when you were at a general store, someone asked for your suggestion on whether he should opt for a DVD-RW or simply a dual layered disc. If you are one of those people who are technologically illiterate, well, dual layered discs might have been your answer without even asking the person what he tends to do with them.

It is very important that you familiarize yourself with the various DVD copying terms. Many people are actually confused when it comes to copying DVDs since they simply don’t know which formats are actually meant for them and most importantly, the various terms used for the same.

Given below are some of the common terms that you may come across with respect to copying DVDs.

AC – 3 was earlier referred to as Audio Coding 3. However, nowadays, when someone uses the term AC – 3, it generally means Dolby Digital. Dolby Digital is nothing but a technology that allows the user to compress audio and giving the user the ability of encoding six channels with bitrates that measure 448 bits per second.

AAC is bound to be the proper descendant of the AC 3 technology, which promises to bring about various improvements in many areas that its predecessor lacked in.

BUP file is an acronym for the Back Up file, and well, the name explains it all. It actually is a back up of the IFO file type, i.e., Information file that is usually found in DVDs.

Burning a movie on one disc may prove to be a bit difficult if you don’t know the kind of discs available in the market. These discs would include the standard 5 GB discs and the dual layered 9 GB disc. These DVDs are also known as DVD5 and DVD9 respectively. It is obvious that you can fit in an entire movie in the DVD9 without any need for compression, but when it comes to copying a movie in the DVD5, there will be certain amount of data that will be compressed. And if there is no compression option available, the data will be copied in two CDs.

CSS is one term that you are bound to come across with respect to copying DVDs. CSS is an acronym for Content Scrambling System which is generally concerned with the video files that are stored in the DVDs. The CSS technology has been programmed to near perfection in order to prevent users from copying copy protected DVDs.

That’s why, most of the commercial DVDs that are available in the market are aptly protected by the CSS technology. If you really want to know what the CSS technology is actually used for, simply start by playing a DVD movie on a software DVD player. Then after closing the player, simply copy the 1 GB VOB file from the DVD to the computer hard disk.

Now, if you play the movie in your software DVD player, you will find many blocks appearing in the video, which means that you simply cannot watch the video at all. However, at the same time, you will also see some parts of the video that have not been encrypted.

Compressing is when an application compresses the data so that it can fit in with the limited storage space available. The compression application is the best way to fit in a movie in a disc, however, if you compress the movie, some of the video quality is lost in the process.

Therefore, in order to ensure the quality of the video, it is advised that that you get rid of the bonus scenes so that the amount of data that needs to be compressed will be less. One thing that you have to remember is that the larger the amount of data on the disc, the more it will be compressed which will then affect the video quality severely.

Therefore, users are provided with the option of customizing the compression settings so that they are assured that not much of the video quality is affected. With respect to compression settings, the user has the option of selecting the amount of data that needs to be compressed.

Descrambling is nothing but just the opposite of scrambling. In scrambling, the video quality appears in the form of blocks making the video completely unwatchable. However, in case of the descrambling process, descramblers are made available to the users in order to assure that the video quality of the movie doesn’t get affected. When the video is scrambled, a sentence usually becomes two to three digits and when the picture is descrambled, the digits are again arranged into the letters as they were before.

Many DVDs either offer the user to save or even omit the bonus features available. Another feature of some of the DV softwares is that it even allows the user to burn his DVD even though it is scratched. As you might have guessed that some DVDs are very prone to scratches but these programs are adept in restoring even that information during the copying process.
