See those commandlines!
1) For divx & xvid he specifies target bitrates but sets a constant quantizer 
(vqscale=2) for lavc while gives no reason for this.

2) Different keyframe intervals. 50 constant for divx, 50 min for xvid, 20 
(???) for lavc.

3) For divx he tells to use the best quality (q=5), for xvid he only enables 
4mv and for lavc only vhq. I believe that it'd would had been (at least 
"more" correct) to do with "vhq=1:4mv" (or higher vhq, but it might bring 
more speed problems) for xvid. For lavc "vhq:trellis:v4mv" or more.

I also wonder if more lavc (& xvid) options should be enabled to match the 
amount of options used in divx with best quality. Eg bframes, vlelim & vcelim 
etc.

Please correct me about xvid, I haven't ever used it so I haven't quite read 
about it's encoding options.

Afaik doom9 hasn't ever heard about lavc or o-p-e-n-s-o-u-r-c-e or even 
mplayer. Of course I can be wrong, I haven't visited it for some time.
