I will try adding vqcomp=0.7 like you suggested. I notice that
most artifacts I get are in the high-motion scenes, and if I
understand vqcomp correctly, increasing its value from the
default 0.5 should help with those scenes.
However, I also noticed that with lavc, the only way for B-frames
to be handled correctly is to add vb_strategy=1 (and vmax_b_frames=2,
otherwise it won't use B-frames at all). Have you considered this?
XviD does not seem to have any problems using B-frames correctly, ie,
avoiding them in high-motion scenes.

Could you elaborate further on this, please? You mean that for the
first pass it is better to use vqscale, and vbitrate only for the
second pass? I am following the instructions from Mplayer's docs,
but they seem a bit out of date, alas.
Thanks in advance!
