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 t= he H.264 video codec with MP3 sound, which makes it a lot smaller. The first s= tep 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=3D704:416:10:80).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=3D4:bframes=3D3:b_pyramid:weight_b:qp=3D18:threads=3Dauto= :pass=3D1 \ -idx -oac mp3lame -vf crop=3D704:416:10:80 -o /dev/null; \ mencoder title.mpg -ovc x264 -x264encopts \ subq=3D6:partitions=3Dall:8x8dct:me=3Dumh:frameref=3D5:bframes=3D3:\ b_pyramid:weight_b:qp=3D18:threads=3Dauto:pass=3D2 -vf crop=3D704:416:10:80= \ -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.
