A DVD movie will not play
Make sure that the label or side you want to play is facing up, then try
again.
Shut down and restart your notebook.
Clean the DVD. For more information, see

DVD discs and drives contain regional codes that help control DVD title
exports and help reduce illegal disc distribution. To be able to play a DVD,
the disc's regional code and your DVD/CD-RW or DVD-RW/CD-RW drive's
regional code must match.
The regional code on your DVD/CD-RW or DVD-RW/CD-RW drive is
determined by your notebook's delivery address. The regional code for the
United States and Canada is 1. The regional code for Mexico is 4. Your
DVD/CD-RW or DVD-RW/CD-RW drive's regional code must match the
regional code of the disc. The regional code for the disc is on the disc, disc
documentation, or packaging.
If the DVD movie does not play, the disc's regional code and your
DVD/CD-RW or DVD-RW/CD-RW drive's regional code may not match.
Make sure that the InterVideo program has been installed on your
notebook. See
A DVD does not produce sound on a TV
Audio is not transmitted through the S-Video out jack. Use the built-in
speakers, a set of headphones or external powered speakers, or connect
your notebook to a stereo system to hear sound while playing a DVD.
