DVD player in Windows 10

Posted in Computers, software, technology with tags , on June 12, 2016 by marksun

Recently learned that Windows 10 does not ship with a DVD player and that an upgrade to Windows 10 kills DVD playback.

 

Microsoft stopped DVD support in Windows 8 and continues in Windows 10. The reason are patent protections for key software components:

  1. MPEG-2 decoder.  A manufacturer must pay $2 per copy of this software.
  2. Dobly digitial audio:

You can get around this by using VLC as a player.  This may also be the case with apple whose video players do not carry a license for Microsofts old .msi format.  VLC is a free open source cross platform that circumvents patents by an interestering assertion:

Patents and codec licenses Neither French law nor European conventions recognize software as patentable (see French section below).

Therefore, software patents licenses do not apply on VideoLAN software.

VLC contains the following:
libdvdcss – find and guess keys from DVD to decrypt it
libaacs – advanced access content system
