It really depends on what format the files are in at the moment which will determine what needs to be done with them. I'll assume you've obtained them legitimately. There are several ways you might want to do it. You may want a menu to skip directly to a specific cartoon, or you may not. You may want to be able to seperate the cartoons in such a way so as pressing skip chapter will skip to the next cartoon, or you may want it to play like a video cassette, with just the added benefit of instant rewind lol. Which of these would you like to have? And what format are the files in at present (AVIcodec can help if you're unsure)?
