Hi to all,
                first of all I would say thank you very much to the authors, for this \
wonderful program (Mplayer - Mencoder). I am a newbie in linux and I tryed a couple \
of ripping with lavc as codec (I used to do with DivxPro in Win$) What i should say \
is that lavc works very very well. I have done some test ripping movie in only 1 CD. \
Working for 2 CD is easyer to reach good quality even for a non good codec but run \
for 1CD it will show immediately how difficult could be to obtain good results. With \
lavc I obtained very good results even with less bitrate. So thank you very much for \
this great job. 

What I did not succed is to encode the credits with a different quantizer; mainly \
because I did not succed to point the start frame and the end frames. Here are my \
                command lines:
Rip: mplayer -dvd 1 -dumpstream -dumpfile foo.vob. This produce a single file >4Gb 
Audio: mencoder foo.vob -aid 129 -ovc frameno -o frameno.avi -oac mp3lame -lameopts \
preset=128 Encoding video: mencoder foo.vob -oac copy -o /dev/null -ovc lavc \
-lavcopts vcodec=mpeg4:vbitrate 916:vpass=1:vhq:v4mv:trell -vop scale 640:272, \
crop...... The second pass the same with vpass=2 and -o final.avi   (Here I cutted \
the vrc_override options..)

Well, I tryed to seek the start frames by looking at the time/frames in the shell \
while Mplayer is running (command: Mplayer foo.vob) but without success because \
somewhere in the movie, the time turns to zero (i.e: by pushing mplayer forward with \
the right arrow, the time does not increase linearly); My movie is about 2:34:00 long \
but at about 1:29:00 the time turns to zero. In addition if I try to start mplayer \
from a point later than 1:29:00 it exit immediately (command mplayer foo.vob -ss \
1:35:00 for example) Probably this could be related to the file foo.vob made by the \
ripping process. Any hint? In conclusion I am asking: how are you doing this job? 
Thank you very much in advance for help.
Best Regards,
Roberto
