Just for me, as I don’t want to forget how to rip difficult/corrupted DVD VOB files:

sudo mount -o loop file.iso /mnt
export IN=”/mnt/VIDEO_TS/VTS_01_1.VOB”
export OUT=”vob01_1.avi”

mplayer “${IN}” -identify
mplayer “${IN}” -aid 128 -ao pcm:file=audio_es.wav -vc dummy -vo null
mplayer “${IN}” -aid 129 -ao pcm:file=audio_en.wav -vc dummy -vo null

Choose one:

mencoder “${IN}” -nosound -noautosub -mc 0 -ovc lavc -lavcopts vcodec=mpeg2video:vbitrate=6000:ilme:ildct -o video.avi
mencoder “${IN}” -nosound -noautosub -mc 0 -vf pp=ci,scale=720:576 -ovc lavc -lavcopts vcodec=mpeg2video:vbitrate=6000:ilme:ildct -o video.avi
mencoder “${IN}” -nosound -noautosub -mc 0 -vf pp=ci,scale=720:576 -ovc xvid -xvidencopts bvhq=1:chroma_opt:quant_type=mpeg:bitrate=1000 -o video.avi
mencoder “${IN}” -nosound -noautosub -mc 0 -vf pp=ci,scale=720:576,crop=704:416:10:82 -ovc xvid -xvidencopts bvhq=1:chroma_opt:quant_type=mpeg:bitrate=1000 -o video.avi

ffmpeg -vcodec copy -i video.avi -acodec copy -i audio_es.wav “${OUT}” -newaudio -acodec copy -i audio_en.wav

You can use “mplayer file.avi -vf cropdetect” to find out the crop parameters

Concatenate all avi files:
avimerge -o final.avi -i first_file.avi second_file.avi
