No surprise about its content : all initially planned features are there :

  XSUB subtitles let you author movies with multiple language subtitle sets ;
  interactive video menus offer unprecedented convenience and control so you can quickly navigate between various scenes or bonus features, and select from audio track and subtitle options ;
  chapter points provide flexibility, allowing you to jump straight to the scene you want to watch from anywhere within the video ;
  alternate audio tracks enable audio tracks in multiple language versions or separate audio tracks for specific speaker configurations ;
  XTAG video tags contain descriptive information like title, author and the video specifications used in the file’s creation to streamline organization ;
  the .divx file extension clearly identifies content in the DivX format so you’ll never again be left wondering whether that .avi file will really play in your DivX® Certified device.

Divx Networks confirms that the file size can be up to 40% lighter than the previous codec version. That’s probably very optimistic, but there’s one aspect which is obvious : based on the same file size, the compression is visibly much better than Divx 5.

Many standalone players are already partially compatible . None is able to support the menus for the time being. However this new format is now finalized, and that will enable the manufacturers start selling fully compatible players (hopefully soon). It is still unclear if this compatibility can be achieved with a simple firmware update.

Divx6 is now also described as Divx Media format.
