Arrrgh great point. I was doing multipass! (2 pass). So I guess was wasting 
time doing the filters twice! :( 

I know what you mean and I plan to use HuffYuv as the intermediate file. I 
just don't know how to accomplish this. This my current code (2 pass):

mencoder dvd://4 -chapter 11-11 \
        -af volume=9 \
        -ffourcc DX50 \
        -vf crop=704:480:0:0,yadif=3:1,mcdeint=2:1:10,framestep=2
       -oac mp3lame \
       -lameopts cbr:br=128 \
       -ovc lavc \ 
       -lavcoptsvcodec=mpeg4:lots-of-options:vpass=1 \
       -o "/dev/null"

mencoder dvd://4 -chapter 11-11 \
        -af volume=9 \
        -ffourcc DX50 \
        -vf crop=704:480:0:0,yadif=3:1,mcdeint=2:1:10,framestep=2
       -oac mp3lame \
       -lameopts cbr:br=128 \
       -ovc lavc \ 
       -lavcoptsvcodec=mpeg4:lots-of-options:vpass=2 \
       -o "/home/jorge/rio.avi"


In order to do what you suggest I guess I obviously need to:

1) change /dev/null to the huffyuv (ffvhuff) file (whatever.avi)
2) change source file on 2nd pass from DVD to the actual huffyuv file

I just don't know how the divx2pass.log is generated on 1st pass (to be read 
by 2nd pass) if I'm using different video codecs on the 2 passes?

something like this?

mencoder dvd://4 -chapter 11-11 \
        -af volume=9 \
        -ffourcc DX50 \
        -vf crop=704:480:0:0,yadif=3:1,mcdeint=2:1:10,framestep=2
       -oac mp3lame \
       -lameopts cbr:br=128 \
       -ovc lavc \ 
        -lavcopts vcodec=ffvhuff:vstrict=0:vpass=1 \
       -o "/home/jorge/intermediate.avi"

mencoder /home/jorge/intermediate.avi \
        -af volume=9 \
        -ffourcc DX50 \
        -vf crop=704:480:0:0,yadif=3:1,mcdeint=2:1:10,framestep=2
       -oac mp3lame \
       -lameopts cbr:br=128 \
       -ovc lavc \ 
       -lavcoptsvcodec=mpeg4:lots-of-options:vpass=2 \
       -o "/home/jorge/rio.avi"

Thanks for the help!
