I have alot of kid video's in iso format on my computer that I am converting to mp4's to put on their tablets. I have been using handbrake to convert them, but I just noticed it will only convert one title into one file. Which is not what I want. So, for example the geo trax dvd iso I have has 8 10 minute titles in it. I only want one file not 8. I don't believe handbrake can do this. Is there another program I can use to batch convert iso's some with multiple titles into one mp4's per iso?
