How to Reinstall Codecs for Windows XP
Audio and video codecs allow you to view, to listen to and to manipulate different types of multimedia files on your computer. Codecs range from Windows Media and its built-in codecs system to third-party codecs such as DivX and XviD. Outdated or damaged codecs may cause your computer to be unable to correctly play audio and video files, or you may experience problems when encoding a multimedia file. Prior to reinstalling a codecs package, you should uninstall the current codec, or you may continue to experience problems.
