What you said makes sense with the docs. So probably it's supposed to work.

My command-line so far (working with a direct CVS compile on Windows, dated Feb 
29th) is this:

BATCH 
===== 
mencoder -include settings.ini -lavcopts keyint=15 movie.vob -o movie.mpg 
bbdmux movie.mpg 0xe0 movie.m2v 
del /q /f movie.mpg 

SETTINGS.INI 
========= 
of=mpeg=1 
ovc=lavc=1 
vf=hqdn3d=4:3:6 
noskip=1 
nosound=1 
lavcopts=vcodec=mpeg2video:ildct=1:ilme=1:vstrict=-1: 
vrc_buf_size=1835:vqcomp=0:vqblur=0: preme=2:ildctcmp=2: precmp=2: 
vqmax=10:mbqmax=10:vbitrate=300:vrc_minrate=300: 
vrc_maxrate=9800:scplx_mask=0.3:autoaspect=1

It's for 1-pass encodings and I'm pretty happy with the quality. I only found a 
dark area on a face inside a sub doing tests with "The Abyss" that could have 
looked better, probably by reducing scplx_mask=0.3 . All other films I tested 
looked great, including some dirty anime tests (interlaced with blended fields).
Strangely it works better ( in terms of quality and filesize ) without B-frames 
than with B-frames!

vstrict=-1 was needed in this build because it wouldn't let us do 29.97fps or 
23.976fps without it. According to docs it should have been vstrict=0 .


Do you have any other ideas on how to keep telecined output?
