these are the current "nextgen divx" codecs :
Project Mayo, 3ivx, LoadVideo, Oyster, OpenCodex
Indeed chrassig, divx deux is the "official new one" but i dont believe the original team is working on it. The original makers of divx got quit scared of the divx impact, and they decided to stay quiet for a while, though that they give advice to the new programmers..
Thats what i heard....
