sorry first...

for mencoder, i use:

/usr/local/mplayer/bin/mencoder /tmp/3.wmv -oac mp3lame -vf
scale=320:240,harddup -lavcopts
-of lavf -lameopts br=64 -ovc lavc -ofps 25 -srate 22050 -o /tmp/out.flv

for ffmpeg, i use:

ffmpeg -i /tmp/3.wmv -y -ab 64 -ar 22050 -b 200 -r 25 -s 320*240 /tmp/out.flv

i found that the A/V sync of mencoder is a little bit out of sync
(very little, BUT noticable), while ffmpeg is okay. Of coz I can use
ffmpeg, but ffmpeg's support of WMV is not as good as Mencoder...

Thanks for any comment...
