ahh, and you think i should pull the audio from the dvd on the third
pass...  that SHOULDN'T make a difference, but I will try none the less,
just so I can say I've exausted that option :)  If it does make a
difference, wouldn't that be considered a bug?  I have experienced this
lag problem with two pass and single pass encoding, so I don't expect that
to be the problem.

>> mencoder -dvd 1 -ovc frameno -o frameno.avi -oac mp3lame -lameopts
>> preset=standard
>>
>> rm divx2pass.log && mencoder -dvd 1 -o /dev/null -ovc lavc -lavcopts
>> vcodec=mpeg4:vhq:keyint=150:vbitrate=870:vpass=1 -vop
>> crop=640:268:0:44,scale -zoom -xy 640 -oac copy
>>
>> mencoder -dvd 1 -o output.avi -ovc lavc -lavcopts
>> vcodec=mpeg4:vhq:keyint=150:vbitrate=870:vpass=2 -vop
>> crop=640:268:0:44,scale -zoom -xy 640 -oac copy
