DivX is a MPEG-4 implementation. DivX Networks claims it is MPEG4 compatible. 
XviD is a GPL'd MPEG-4 codec, and it's FAQ says it is ISO MPEG-4 compliant.

Some say XviD is a better codec then DivX. I have no opinion. It has been 
gaining popularity as the codec to use for DVD rips. Not that I'd know 
anything about that. No sir, I'm a good little consumer. (Actualy, very few 
movies are worth the trouble to download...)
