Windows Essentials Media Codec Pack
The Windows Essentials Media Codec Pack contains DirectShow codecs for a wide range of media that Windows Media Player doesn't naturally recognize or support. It also includes DVD codecs which are necessary if you install a DVD drive on a computer that didn't come with one. Supported file formats include MP4, DivX, HD-MOV, MPEG-1/2, OGG/OGM, Vorbis, XviD and more. The codec pack does not include a media player. After installation of the codec pack, you can test it to see what types of files you can play. To perform the test, open Windows Media Player, then open the media file you would like to play or insert a disk into your CD or DVD drive. If the correct codec for that file is included with the pack, the files will play properly in Windows Media Player.
