Q: fix windows media player, remove error code(cood1199)

 Incountered Dummydecoder in my windows cd&dvd player site that is blocking loading and playing where did it come from since I don't use blueray on my system?



Hi Koolhand,


  • Did you make any changes to the computer before this issue started?
  • Do you have Itunes or Apple related softwares installed on the computer?


Windows Media Player cannot play the file. You might encounter this error message for one of the following reasons:


§ The file type is not supported by the Player. For a list of file types (formats) that are supported by Windows Media Player, see Supported file types.

§ The file type is supported by the Player, but the file was compressed by using a codec that is not supported by the Player.

§ Your sound card or sound controller is not configured properly. Try changing the audio output device associated with the Player.


You may access the link below and follow the steps in the article to change the Audio output device and check if it helps you fix the issue.


If you have Itunes or any Apple related software on your comptuer, you may uninstall it and reinstall the software and

check if it helps.


Hope this helps. Let us know the results.


Thanks and Regards,
