Can't watch DVD movies in Media Center

[Guest]

Hi,
I can't watch movies in Media Center. I use Media Center Play DVD and I get
message: Decoder Error The video decoder has either malfunctioned or is not
installed. Please restart Media Center and/or computer when I try to watch
DVD

Any idea what's happening?

Have you reinstalled your DVD decoding software? It's usually a version of
PowerDVD or WinDVD

Yes, I have WinDVD installed and movies are played in this program but in
media center they don't play.
