DivX 6 marks a new era in DivX history. Where before DivX was simply a codec technology, today we expand the DivX universe and add the DivX Media Format to our media ecosystem. Bringing with it advanced media features such as alternate audio tracks, multiple XSUB(tm) subtitle streams, XTAG(tm) video tags, chapter points, interactive video menus with scene selection, multiple titles and more, the DivX Media Format creates a true home theater experience both on and off the desktop.

DivX helium was also released, the beta version can be found here. Helium takes advantage of multi-thread capable systems, like SMP multi-processors, HyperThreaded and dual-core processors.
DivX Helium codec demonstrates our latest research into processor optimization, achieving encoding times up to twice as fast as DivX 6 in the highest quality (Insane) mode when run on dual core, HT and SMP CPUs.
