Not sure how much of a help it is, but ages ago I was playing about with
linux avi/mpeg - dvd ripping etc.. and did write up a couple of notes on the
matter and placed on my site.  Again not sure how much help they are, was
doing it in 2005 but now do not rip dvd's anymore since dvd's are cheaper
now than cd to backup incase of any scratches.
