I’ve been using the latest version of HandBrake, but I’m having problems ripping a particular DVD. I tried scanning 99 titles, and after that ordeal, I ended up with a video with no sound, a mixed-up video, then it was cut short. Any remedies?

First, our admonition on DVD ripping: the British Board of Film Classification and most media companies argue that you can’t legally copy or convert commercial DVDs for any reason. We (and others) think that, if you own a DVD, you should be able to override its copy protection to make a backup copy or to convert its content for viewing on your other devices. Currently, the law isn’t entirely clear one way or the other. So our advice is:

if you don’t own it, don’t do it. If you do own it, think before you rip. And if the disc includes a digital copy compatible with iTunes, use that instead.

Apple’s DVD Player application will tell you which is a DVD’s real main title

Now that you’ve taken that to heart, here’s what’s going on. You’ve encountered a copy protection measure that’s increasingly being used by the creators of these discs. Discs like this list multiple instances of a main feature title, all with different lengths. But only one of them is the real thing. HandBrake does its best to guess the correct one, but it often fails, leaving you with the kind of out-of-whack movie you’ve described. So, the trick is discovering the real title.

To do that, insert the DVD and let Apple’s DVD Player application play it. Skip through previews and commercials before you can watch the movie. When the main feature finally begins playing, push your cursor to the top of the display to reveal the menu bar. From that menu bar choose Go > Title (you can also Control-click or right-click on a movie and choose Title from the contextual menu). Scan the long list of titles, and you’ll see a checkmark next to one of them. This is the number of the disc’s real main title. Make a note of it. Now return to HandBrake and instruct it to rip this title as the main feature. All should be well.
