I apologize this is the wrong category for this question. However, I've seen that the developer has posted here before, so I thought it may help. I have several .m4v files that are around 10-15 mins each without any chapters. I want to join them using MKVtools - simple enough. BUT, I was hoping that once I join them, I would be able to use the chapter skip button to skip to the next file (within the joined file). But this is not the case. It is simply one long file with no chapters. My question is, is it possible to do this with MKVtools, or any other free program for that matter?
