Why we would convert DVD to AVI
At present, DVD disc is currently the dominant consumer video format in some regions. DVD video offers high video/audio quality for users, but with a lot of restrictions. First, it requires a DVD drive and a MPEG2 decoder (MPEG is considered a lossy compression, where some of the information is lost in both the video and audio, but the quality remains almost the same.). Second, each DVD-Video disc contains one or more region codes, denoting the area(s) of the world in which distribution and playback are intended. The commercial DVD player specification dictates that a player must only play discs that contain its region code. Third, it is not as convenient as many videos could be directly stored in computer.
AVI (Audio Video Interleaved) is another common compression format for audio and video files. Like MPEG files, there are various compression schemes that affect the quality, size and device-compatibility of the files. Each of these compression schemes is known as a codec – short for coder-decoder, which is basically what a codec does. The various codecs bundled within the best DVD to AVI converter software will code your DVD files to be decoded by the devices that play AVI files.
