Boy, I haven't been keeping track, but it looks like the linux tools
for dvd backup might be getting there. When I first started playing with this
slightly over a year ago (after I was given a DVD burner as a gift), the linux
tools were way too crude to do the extraction/recombination without heroic
efforts. The end result usually had bad sync, and took 12+ hours of crunching
to make it fit. I (very reluctantly and irritatingly) had to find Winders
tools to do the job. I knew it was just a matter of time for darwin to evolve
the tools... Maybe it's time to try again... :)
