I have rarely ever had an issue with Handbrake. And on the couple of occasions when I have, I was able to download a nightly that handled the movie. (I think that there was one movie a number of years ago that I had to wait three days until the nightly took care of the issue with ripping it. I don't remember what movie it was, though.)
One thing that I frequently do with Handbrake is to start the movie in DVD Player, check the title being played, then use the 'open specific title' in Handbrake to avoid an issue that seems to be associated with attempting to read certain tracks, like poison pills.
