Well what do you mean by efficient? It does take time to add them to the queue and that happens one at a time. But since it takes time to convert every one, I just grab a cup of coffee and roll through them. Once they're in the queue, then it just grinds away. I do 20 movies at a time converting from the VOB deprotected format of the DVD to mp4 for my tablets and phone. Once I fill up the queue, it takes a couple hours to clear and then I just add more.
