Hi,
To resolve this problem, you will have to assign the default action for each type of disk that you try to play in the disk drive.
To do this, right-click on the icon for "CD drive" in "My Computer" and select "Properties"
Then click on "Autoplay" tab. (See attached image)
Then select the type of files "Music, video, Mixed content,etc" from the drop-down menu and click on "Select an Action to Perform"
Then in the options window, choose "Play with Windows Media Player" and click on the "Apply" and "OK" buttons.
Repeat the step for other disk types.
Hope this solves your problem. For more help and clarifications, please feel free to reply to this post.
