Computer users running Windows Media Player 11 (WMP 11) on their Windows XP computers with Service Pack 3, may find that their CDs and/or DVDs are not playing on the new media program. Various factors could be causing the problems, including missing codecs or simply incorrect performance attributes.

Open Windows Media Player 11 on your computer.
Click "Now Playing" on the WMP 11 window. On the drop-down menu, click "More Options." Go to the "Performance" tab and click on it, then click on the "Advanced" button.
See the "Video Acceleration Settings" window, then remove the ticks from both of the "Use overlays" boxes. Try also removing the check mark from the "Use video mixing renderer" box. Click "OK," then return to the "Options" window and click "Apply" and "OK."
Check to see if your computer is missing a required codec, if the preceding section does not fix the problem. A codec is a software program that compresses or decompresses a digital media file. The codec is made up of the encoder and the decoder. Windows Media Player includes some codecs; however, if you are trying to play something that was compressed by a different codec, you may need to download a new codec from the Internet.
Display information about your Player by clicking on the "Help" menu, then the "About Windows Media Player" box, then "Technical Support Information" to see what codecs your computer contains.
Look for information on codecs you might need on the Windows Media codecs FAQ page.
You can "downgrade" or revert back to the previous version of Windows Media Player if you are still unable to use WMP 11 for viewing CDs and DVDs, or if you are simply dissatisfied with the program.
Log on as an administrator and disconnect any portable devices, such as an MP3 player or standalone CD/DVD player, that is hooked up to your computer.
Click "Start," then go to your "Control Panel." Go to "Add or Remove Programs," then "Remove a Program." Click on Windows Media Player 11," then on "Remove." Follow the instructions, then restart your computer. If the previous version of WMP was removed from your computer as an unwanted file, you may not be able to roll back to that version.
Tips and warnings
- Choose a recorded CD or DVD that you know worked in a previous WMP program and put it in your computer while trying remedies to see if it starts playing using one of these methods.
