may be able to fix the problem yourself. 

For general problems playing a DVD or Blu-ray Disc™ title, try the 
following steps:

Verify that the disc is in a format that the drive supports.

Ensure that the disc is properly inserted in the drive tray.

Use the DVD or Blu-ray Disc™ player software that came with 
your computer to view DVD or Blu-ray Disc™ movies.

Clean the disc and try again.

A dirty drive can also cause audio problems. If you have tried 
several discs and all fail, consider sending your drive to an 
authorized service provider to get it cleaned.
