Split mpeg-4 movies by the chapter

I have often a tedious job where I need to split movies by the chapter. (The videos have multiple audio tracks & subtitles and have defined chapters) I can do this in Quicktime, but it's a very manual process !! Therefore I'm looking for a way / app / .... that takes my video and splits it in multiple videos for each chapter. Simple split, no transcoding or anything. (It would be an added bonus if it was possible to alter the id3 meta data in 1 go as well) Again, I can do this - sorta - with Quicktime, but I want a more productive way. Thanks for any feedback !! let me know if you need more info. D
