XviD is a video codec just like DivX. Most new movies and videos are being encoded with XviD.
The XviD Codec is needed to play movies encoded by XviD. XviD is better than DivX.

XviD is the best currently available MPEG-4 video codec solution and additionally XviD is free software!

Changes in XviD 1.1.2 [27.04.2008] :

- Plugh pointed me to another bugfix that made it into CVS but wasn't backported to Xvid-1.1.3. There was an issue with motion vectors (MVs), an array was too small so a wrong MV could have been chosen in some cases. Since those MVs are costly bitrate-wise, it should have happened very seldom. Anyhow, I updated Xvid-1.1.3 and Xvid-1.1.3-VAQ.
