[mythtv-users] Burning DVD from ripped vob files

[papenfuss at juneau.me.vt.edu]

	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... :)
