Windows XP Video Decoder Checkup Utility - why isn't my DVD playing?
|I've seen more than one person come into the
computer help club and ask why Windows Media Player isn't playing
their DVD's. This utility could come in handy when you need to know if you
have a valid decoder.

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.
