Answer: all of them offer a MP3 audio encoder.
- DivX Inc. in San Diego, CA
- Xvid Solutions in Hof, Germany
- XviD, the open source project on SourceForge
All of them offer an MPEG4 Advanced Simple Profile (ASP) video encoder. The Xvid Solutions encoder is the same as the XviD open-source encoder and often appears in free software. The DivX encoder is proprietary and only appears in DivX Certified software such as the free DivX Converter
