I've had similar problems encoding to mpeg1 (-ovc lavc -lavcopts 
vcodec=mpeg1video:vbitrate=1150) seems to give me variable bitrate instead 
of constant (using a recent CVS version). I have been using resizing filters 
as well, so that _could _ be the problem.

this should depend on the codecs rather than the operating system. 
mencoder/mplayer tends to be more flexible with stardards than other 
software, so maybe it has encoded your video into a slightly nonstandard 
format.
