AVI Codec Pack is a collection of codecs provided by Streaming Media Tech. We have put together two packages optimized for the most common sorts of media available today, such as DivX and XviD Movie files

The Plus package is a collection of codecs and filters. Codecs are needed for encoding (and decoding) audio and video. During the installation you get to choose which components to install, and after installation you will be able to play encoded media right away. The Lite package is an smaller collection of codecs and filters. Codecs are needed for encoding (and decoding) audio and video. Even though the lite package is very small in size, it will allow you to play all most audio and video formats, including DivX, XviD, OGG and many more. Like The Plus package, during the installation you get to choose which components to install, and after installation you will be able to play encoded media right away.
