I tried 
mencoder -tv
on:driver=v4l:device=/dev/video0:width=480:height=576:adevice=/dev/dsp:
forcechan=2:outfmt=yuy2 -ovc lavc  -vop pp=lb  -oac mp3lame -lameopts
cbr:mode=0:br=128  -o output.avi

But this do not work with linux-dvb.2003-02-02-ci-ll ( and earlier ).
I think Marcus use "his own" version of drivers :), am i right ?

Mencoder gives me this output:
