Windows Media Player cannot play DVD

Windows Media Player cannot play the DVD because a compatible DVD decoder is not installed on your computer

You get this error message if you try to play a DVD on a computer with Windows Media Player that has not been upgraded to play DVDs. Your computer is missing so called DVD decoder.

How can I find out if I have DVD decoder?

Go to your Start menu and click Run.

Then, type dvdupgrd /detect and press ENTER.

After you run the dvdupgrd /detect command, any detected DVD decoders will be listed in a message box.

How do I upgrade my DVD decoder?

Before you try upgrading your computer, read the section below and check the Microsoft website for compatibility. If an upgrade is available for your DVD decoder program, then do the following steps:

Go to your Start menu and click Run.

Then, type dvdupgrd /upgrade and press ENTER.

After you run the dvdupgrd /upgrade command, you will be directed to the manufacturer's Web site where the upgrade is located. Follow the instructions on the Web site to obtain and install the upgrade for your DVD decoder program.

After you are done, you can run the dbdupgrd /detect command and check if the decoder has been upgraded. If yes, you should see something similar to the following screen:

Upgrade did not work - what to try next?

It can happen that after you upgrade the decoder, you are still unable to play DVDs. In that case, try upgrading your codecs. Installing the k-lite codec pack usually solves most problems.
