Yes, I know. I also didn't know it until I suddenly was _very_ upset from
this crazy medion card. And then everything happens usually very, very
quickly at me... ;-)

Well I finished earlier as expected, but mencoder meant that it does not know
'-vf' and aborted. I must try to understand all these options first, so I'll
play around with them by myself to see how I can optimize.

I also have found meanwhile a command line which basically works (making
DivX), but I have no sound. It reads as follows, also everything
as one line...
mencoder -tv on:driver=v4l:width=768:height=576 -ovc lavc -lavcopts \
vcodec=mpeg4:vbitrate=900 -oac mp3lame -lameopts cbr:br=64 -vop \
pp=lb,crop=720:544:24:16 -o output.avi

Maybe this is of importance: The Hauppauge has a bridge cable to LineIn of the
Soundcard. Can this be the reason?

Another thing is: The above script _records_ (not good, but for first steps
it is ok), on an Celeron 1700 it also reaches nearely permanent 25fps, but:
How do I stop it correctly? Hitting ^C stops, but this is surely not the
right way, because mencoder cannot finish its work, I guess.
