  <title>Problem with playing movies from a DVD</title>

  <p>
  It may happen that after putting a DVD into your CD/DVD drive, <app>Videos</app>
  shows the error message <gui>An error occurred ‒ The movie could not be read.</gui>
  This may be because your <link xref="supported-formats">a required 
  <sys>GStreamer</sys> plugin to read the format of the movie is not installed
  on your system</link>, or because DVD is encrypted and a DVD decryption package
  is not installed on your system.
  </p>

  <note style="tip">
    <p>To open encrypted DVDs, consider installing the <sys>libdvdcss</sys>
    package. However, note that using this package is not legal in all countries.
    For further information if or where the package might be available for your
    distribution, please ask in a support forum of your distribution.</p>
