I downloaded 25 episodes of Death Note to put on my iPod, but they are all MKVs. I have tried 3 different converters: Daniusoft, Emicsoft, and one other. All of them will only convert 3-5 minutes of video unless I buy the full version. Each episode is around 22-23 minutes long. I am not using a Mac (if that matters), and I am not paying $40 just to use those converters once. Is there any free converter that can manage entire episodes, not just 5 minutes?
