I don't know, but I have recreated the IFO files and it works well now.

Here is how I have recreated the IFO files for those who doesn't know how to 
do it (I have searched these informations during 1 week) :

lets say your dvd drive is accessable at /dev/dvd, the saving directory 
is /movies/movie1 and you want to backup title 1, all chapters with 1st video 
and 1st audio track:
 -> dvdauthor -t -o /movies/movie1 -f 'streamdvd -i /dev/dvd -t 1 -s 0xe0,0x80 
|'
 After that, build the missing ifo files with:
 -> dvdauthor -T -o /movies/movie1
 That's it :-)

These lines were copy/pasted from here : http://www.badabum.de/streamdvd.html

Hope it will help some people.
