There can be an alternative way to make a Mkv of your favourite DVD.
1. Make an image of your whole DVD on your hard drive with this command : dd if=/dev/sr0 of=nameoftheDVD.iso sr0 is my DVD player, it can be something else for you.2. Mount your iso image. You can also play it to see if there's something wrong at the 30st minute.
3. Encode your DVD with Handbrake I also tried SimpleBurn but it didn't work for shortest movies in the DVD.
