Well, here is the info about my system: 

distro: SuSE 8.2

kernel: linux 2.4.20-4GB-athlon

libc: /lib/libc.so.6

X version: XFree86 Version 4.3.0

ld version: GNU ld versión 2.13.90.0.18 20030121 (SuSE Linux)

I ran Mencoder with the following command:

mencoder -nosound -ovc lavc -fps 25 -ofps 25 -lavcopts 
vcodec=mpeg2video:vbitrate=1200:vqmin=1:vrc_buf_size=230:vrc_minrate=500:vrc_maxrate=2000\

hqdn3d,scale=480:576 -of mpeg -o test_out.mpg test.mpg
