I know the whole delay thing, since I'm much more experienced in DVDrippin 
under win than Linux. Otherwise I didn't have problems on transcoding the 
last 3 DVDs. But atlantis I didn't tested right now, since I have work since 
3 weeks and it is very hard to work 8 hours a day , then you haven't done it 
since 3 years before *g ( student ;) )
