divx3 is msmpeg4 (a pre mpeg4 format by ms). but thats the past. divx5 and xvid are using the offical mpeg4-2 (h.263) video standard (i think comperable to wmv8).
wmv9 is on the other hand like next generation. it's kinda ms version of mpeg4-10 (h.264 or AVC) video standard. needs more cpu power, but have better compression rate (at least this would be the point of next generation...) mpeg4-10 is not widespread yet, needs more time to have advanced encoders like the current mpeg4-2 ones. but it's an open format vs the closed format of ms.
btw BetaPlayer can now play wmv files too (with the original ms codec). it's preliminary, but you will have better visual quality, because of real 16bit rgb (wmp uses 15bit) and dithering and adjustable color settings. but only works on wm2003 and above, no drm, no streaming...
