ubuntu-10.10

I have a .vob file that has bee ripped from a dvd, when I watch the .vob its very good quality video and 5.1 english audio but when I use ffmpeg it has rubbish video and mono french audio.

That was using this command:

ffmpeg -i /samba/ripping/vobs/12161840#2.vob -f avi /samba/ripping/avis/test.avi

I've tried a few different variations on that but it never comes back with anything good just bigger files with bad video and incorrect sound.

I know the videos good and the correct audio streams exist so how do I select a 5.1 track and get good video?

ffmpeg gives the .vob details as:

Input #0, mpeg, from '/samba/ripping/vobs/12161840#2.vob':
