i had orginally tried
mencoder ....nuv -oac mp3lame -ovc divx4 -o ....avi
and it was gettin avi files around 200 megs for 1/2 an hour that would play in windows but get out of sync very quickly. what worked for me was simply "-oac copy" instead. i think it was because the bitrate was different 32k verse 44k as you said. but i'm not sure. with those options it works perfectly for me.
plus since i'm using hardware mjpeg encoding i want to encode to divx4 or something else before i go transfering them around the network anyways. (1.8 gigs decimation 2 q 80 verse .2 gigs defaults)
i'm not sure if that helps, but at least you know it can work : )
