The Windows XP Video Decoder Checkup Utility helps you determine if an MPEG-2 video decoder (also called a DVD decoder) is installed on your Windows XP computer and whether or not the decoder is compatible with Windows Media Player 10 and Windows XP Media Center Edition.

An MPEG-2 decoder is software that allows you to play DVDs and files that contain video content that was encoded in the MPEG-2 format (such as DVR-MS files, MPG files, and some AVI files).

If you encounter a problem while using Windows Media Player 10 to play a DVD or to synchronize (copy) recorded TV shows to a Portable Media Center or other device, use this utility to verify that you have a compatible MPEG-2 decoder installed on your computer.
