the fast & the furious giving you trouble? hmmmm I'm sure I did a rip of that just last week.
Make sure you go over the ripping part better. Also don't just stick the DVD rom in & open up smart ripper right away. Let it load in your drive first, then open up smart ripper & at the start you should notice a small popup window that has all the vob/bup/ifo files read. If not, open the movie up first (say with winDVD) with your player, then close it & then run smart ripper. If everything is checked properly in smart ripper, you should be good to go. Otherwise post back again.
