Any idea why:

mencoder -oac copy -o /dev/null -ovc lavc -lavcopts 
vcodec=mpeg4:vbitrate=1794:mbd=2:vpass=1 -vf 
crop=716:428:2:74,scale=640:272 tower
mencoder -oac copy -o tower1.avi -ovc lavc -lavcopts 
vcodec=mpeg4:vbitrate=1794:mbd=2:vpass=2 -vf 
crop=716:428:2:74,scale=640:272 tower

gave me 50 fps and:

mencoder -oac copy -o /dev/null -ovc lavc -lavcopts 
vcodec=mpeg4:vbitrate=1757:mbd=2:vpass=1 -vf 
crop=716:428:2:74,scale=640:272 -endpos 6236 tower2
mencoder -oac copy -o tower2.avi -ovc lavc -lavcopts 
vcodec=mpeg4:vbitrate=1757:mbd=2:vpass=2 -vf 
crop=716:428:2:74,scale=640:272 -endpos 6236 tower2

is giving me 40 fps? Given that this is the only cpu intensive thing 
I've been doing? (they are discs 1 & 2 of LOTR-2 Towers extended). Audio 
was done exactly the same way...
Cheers
Anton
