If you experience a problem playing DVDs, you may be able to fix 
the problem yourself. 

For general problems playing a DVD 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 player software that came with your computer to 
view DVD movies.

Clean the disc and try again.

A dirty drive can also cause audio problems. If you have tried

authorized service provider to get it cleaned.

clicking Start, and then Computer. The optical disc drive 
should appear in the list.
