Maybe not useless :-)

For other users experimenting with the same in the future. 

With mencode I used the following command (using PAL in my country):

mencoder tv:// -tv
driver=v4l2:input=1:norm=pal:width=640:height=480:device=/dev/video0:
freq=775.25:adevice=/dev/dsp1:forceaudio:audiorate=32000 buffersize=64
-ovc lavc -lavcopts vcodec=mpeg4:vbitrate=400:keyint=30 -oac mp3lame
-lameopts br=32:cbr:mode=3 -ffourcc divx -o "test.avi"

I tried to change the options, but no matter what I did, the result was
poor.

With transcode I used this command:

transcode -x v4l2=resync_margin=1:resync_interval=250,v4l2 -g 640x480
-i /dev/video0 -p /dev/dsp -e 32000,16,2 -N 0x1 -J
resample,levels,smartyuv,pv -w 4000 -y ffmpeg -F mpeg4 -o test.avi

Which results in some larger files, but with excelent quality.

Any advice on how to improve would be greatly appreciated, especially
about the file sizes that transcode produces.
