DVD operating problems

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:

1

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

2

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

3

Use the DVD Player software that came with your computer 
to view DVD movies.

4

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.
