Thank you for posting. This can happen if the Audio track of the DVD is set to something other than what your computer uses. Let's try changing the audio track of the DVD. You can do this in Media player by clicking on the DVD button at the bottom near the
play button. In the pop-up menu you should then see audio, From there you should be able to select different audio tracks.
DVD audio is determined by the speaker configuration you selected in
Set Up Your Speakers, the audio connection type that you use to connect your computer to your speakers or stereo receiver, and the DVD audio settings in
Windows Media Center. For more information about setting up your speakers in
Windows Media Center. Also, the availability of digital audio is dependent on the options that are enabled by the audio hardware that is installed on your computer. For more information about your audio hardware capabilities,
refer to the documentation that came with your computer.
