installed. To confirm if you have Windows XP-compatible DVD decoder
software
on your system:

Click Start  and  Run
Type in : dvdupgrd /detect  than click OK

A Windows dialog box will open with identifying information about the
installed software. If “no decoders found” is displayed, no decoder is
installed and you cannot play DVDs.

programs bundled with it and have nice features.But to play DVDs wit windows media
Player needs only the MPEG decoder and you are done .Enjoy.
