multimedia/transcode is good option as well.  tccat will dump track vob
without borders, use tcprobe to find track you wish to dump.

To both, thanks a bunch for this information.  This is awesome!  I can't
wait to install and try.

Hello

Thanks Roland for the parameters in the mplayer/mencoder...

To make things easier.. I recomend to create a profile 
in the directory ~/.mplayer/mencoder.conf with the content:
=
[pal]
oac=lavc=yes
ovc=lavc=yes
lavcopts=vcodec=mpeg2video:vrc_buf_size=1835:vrc_maxrate=6000:vbitrate=4000
Lavcopts=keyint=15:trell=yes:mbd=2:precmp=2:subcmp=2:cmp=2:dia=-10
lavcopts=predia=-10:cbp=yes:mv0=yes:aspect=16/9
lavcopts=vqmin=1:lmin=1:dc=10:vstrict=0
lavcopts=acodec=ac3:abitrate=192
lavcopts=lumi_mask=0.2:dark_mask=0.15:scplx_mask=0.2:tcplx_mask=0.1
vf=scale=720:576,harddup=yes 
af=lavcresample=48000
mpegopts=format=dvd:tsaf=yes
of=mpeg=yes
srate=48000
channels=2
ofps=25

[pal_cinemascope]
profile=pal
vf=scale=720:432,expand=720:576,harddup=yes 
==

Or using the options from Roland
extract the stream (as Roland said...)  mplayer dvd://1 -dumpstream
-dumpfile dvd.mpg
crop detect...   mplayer -vf cropdetect dvd.mpg

and then finally encode with mencoder using the profile above and
Roland's example...

mencoder -profile pal -vf crop=704:416:10:80 dvd.mpg -o film.mpg

the result will be a high definition video with 1024x576 PAL (25 fps)
16:9 aspect with audio AC3 192Kbps (plays using HDMI)
in any dvd player... or in your computer.
if the source (dvd.mpg) is in 2.35/1 ratio use -profile pal_cinemascope
and mencoder will adjust the aspect for the video.

If you call dd without bs= parameter, the default of 512 is
assumed. This may not be correct for video DVDs. You could
try bs=1m, but I'm not sure what the correct block size for
DVDs is...

For copying them, I always felt comfortable with the vobcopy
tool (for reading), and growisofs -dvd-compat (for writing).
Both tools can be installed via ports or packages.

Just a side note: I don't think /usr/local is a good place
to store DVD images. Some path like /usr/home/dvds would be
good. The /usr/local subtree is "reserved" for locally installed
applications; see "man hier" for details.

My preferred technique is to use mplayer:

mplayer dvd://1 -dumpstream -dumpfile dvd.mpg

Be sure to play the DVD with mplayer to check which track is actually the
movie. Usually it is track #1, but not always.

After copying the stream, I tend to re-encode it for backup purposes with the
H.264 video codec with MP3 sound, which makes it a lot smaller. The first step
is to watch the mpeg and see if there are black stripes around the picture:

mplayer -vf cropdetect dvd.mpg

This will give you a continuous list of crop lines, e.g:
[CROP] Crop area: X: 1..719  Y: 74..500  (-vf crop=704:416:10:80).0

Next step is to re-encode the mpeg file in two steps for enhanced quality,
including the crop information, if any:

mencoder title.mpg -ovc x264 \
-x264encopts subq=4:bframes=3:b_pyramid:weight_b:qp=18:threads=auto:pass=1 \
-idx -oac mp3lame -vf crop=704:416:10:80 -o /dev/null; \
mencoder title.mpg  -ovc x264 -x264encopts \
subq=6:partitions=all:8x8dct:me=umh:frameref=5:bframes=3:\
b_pyramid:weight_b:qp=18:threads=auto:pass=2 -vf crop=704:416:10:80 \
-idx -oac mp3lame -o title.avi;

If you want to include a specific language or subtitle, don't forget to
include the correct options for that; see the mplayer manual.
