DivX 4
DivX 4, released by DivX company, was actually the first DivX version, trademarking the word, DivX. DivX 3's legal status was questionable despite its success and popularity. This led to the development of DivX 4, which was based on the work from OpenDivX (ProjectMayo). DivX 4 has no relation to DivX 3 except for the backward compatibility. DivX 4 uses the fourcc DIVX (as do its successors DivX 5, 6 and 7).
The "DivX" brand is distinct from "DIVX", a former video rental system developed by Circuit City Stores which required special discs and players to function. DivX Codec has become popular due to its ability to compress lengthy video segments into small sizes while maintaining relatively high visual quality.
