Hi,
Here is an image taken from the User Manual for your DVD player.
It shows the type of disks and the audio format that the player supports.
Take notice of the disclaimer shown which states:
''Some DVD±RW/DVD±R or CD-RW/CD-R cannot be played on this unit due to the recording quality or physical condition of the disc, or the characteristics of the recording device and authoring software''
