DivX Video Player & Converter

DivX® is the name of a popular new video compression technology developed by DivX, Inc. The format was developed to enable users to play and create high-quality videos in a fast and convenient way, while still maintaining the best quality possible. The DivX® codec is currently the most popular MPEG-4 based codec because of its quality, speed and efficiency as well as the wide range of DVD players that support the DivX® format.

If you compare DivX movies to DVDs they're able to offer the same image quality at one-tenth (1/10) the size, which makes them perfectly suited for movie downloads where the bandwidth available usually is limited. This means that you can easily fit a full movie on a single CD, while still maintaining the original image quality of the DVD. The video is usually combined with AC3 or MP3 audio to provide both high quality audio and video. All of these things have contributed to the popularity of the format among those that download movies and videos online.
