DVD Copying - The basics [1/2]: "What’s on a DVD?

If you have purchased a DVD that you want to copy, you can put it in your DVD-ROM drive to check out its contents. On the disc you will find several folders with files in it. Normally you should always see a VIDEO_TS and AUDIO_TS folder. The AUDIO_TS folder is used to store DVD Audio, the VIDEO_TS to store DVD Movies.

We will be focusing on a movie DVD, so we’ll enter the VIDEO_TS folder. In this folder you will find .VOB .BUP and .IFO files. The VOB file contains the actual movie files. This is a MPEG-2 encoded file. Simplfied is MPEG-2 is a method of compression for movies, just like MP3 files are compress audio. The file contains also audio, normally this should also be a compressed format. Mainly it is an improved form of MP3, named AC-3. Besides that contain the .VOB files the subtitles and multiple camera angles.

The .IFO files are the information files, used by your DVD playing device. It gives the DVD player information on what .VOB files to load and when. E.g. when to start a new chapter. The .BUP files are simply a backup of the IFO files and generally have no use, they will only be used when an .IFO files become unreadable somehow."

A DVD is normally protected by a code called the CSS encryption. However, the code has been cracked and can be circumvented by numerous software applications. Most of these applications are based on the DeCss software that is illegal in many countries. Removing the protection and getting the movie stored in a hard drive is usually called ripping. Presently, there are many applications available on the market that can successfully rip and burn (copy) a DVD. Splitting and shrinking are the two other options.

Shrinking data is perhaps the most widely used alternative. There are many software programs that can compress data from the original DVD and fit it into a DVD recordable. They are also known as transcoders, encoders or compressor engines. This software can compress data in a way that makes it impossible to decipher whether the DVD copy is actually, a replica or the original. Movie compression is an arduous task for the average PC. With a standard system, compression can take about two hours.

There are other software programs capable of splitting a DVD movie into two or more discs. The disadvantage with these methods is that the user has to continuously change discs while viewing a movie. It is essential to know if the DVD player can play the copied DVD, and whether the DVD is recorded on DVD-R (W) or DVD+R (W) media. A normal home user can create DVD back up in this manner. However, for the advanced user, it is better to research information on the subject and by the best software available.
