DivX Pro 5.1.1 Beta 1 now available, 50% faster than DivX 5.1

Via the DivX Labs website
we can read that a new beta of the DivX 5.1 codec has been released which,
according to the announcement, is a whopping 50% faster than the original DivX
5.1 release. For those of you who don't know what DivX is (shame on you!), it's
a video codec with which you can compress video data to about a tenth of its
original size without sacrificing quality. Here's the changelog for the latest
release:

• Resolved a severe performance hit when using the Deringing mode
  in Postprocessing


• DirectShow filter property page had a cosmetic issue caused by
  using large fonts


• Avoids buffer overuns with extremly small picture sizes (less
  than 80x32)


• Fixed a bug caused by "Auto Post-processing" and
  SMP/HyperThreading CPUs.

New Features:

• Support for generic MP4 FourCC codes which can be
  enabled/disabled in the DirectShow configuration dialog box

Changes:

• Feedback mode can now be globally disabled when it's
  running


• All frames are now displayed in the Feedback windows


• Cosmetic GUI changes have been made to avoid confusion when
  using MV reuse and specfic performance modes


• Deinterlacing is back in the Standard codec


• Added bottom field first encoding


• Smoother DivX logo fade

If you already own DivX Pro, a DivX Beta release will install over
your existing DivX Pro version unless you install it to a different
directory. (You may want to keep a copy of your officially released DivX
Pro codec in case Beta Prototype releases on a 15-day trial, making it
easy for everyone to help improve the codec. If we push out yet another
beta release after your 15 day trial is up , we will create an additional
15-day trial so you can continue using the prototype
version.

If you want to download this latest beta release you can head on over to DivX Labs.
