For the dedication it's probably easier for you to use Sigil after Calibre has converted from rtf to epub. I don't think there is a way to do this using rtf. It can be done if you use txt and markup, but that requires a few more technical hoops to jump through.
If you get chapter detection working then Calibre normally splits each chapter into it's own file.
Is there a converter from RTF to Markdown (I only find Markdown => RTF via google)? I _could_ go with HTML, but then all the escaping codes for quotes and things would drive me nuts. I find it really hard to read HTML when paragraphs are _not_ just a matter of <p> and </p>, with maybe some <em> or <strong> tags thrown in.
I have a copy of The Last Unicorn in LIT that I converted to RTF and then converted again to EPUB. It marked and split the chapters perfectly and I would have thought that one would be harder than the files I had hand edited as the chapter headers were Roman Numerals without any prefix. So I can see that Calibre does do what I want, sometimes. Presumably when I give it a properly formatted RTF input file
What I don't know is why it won't split books that *appear* in all ways possible to be formatted correctly. I even opened some of the books in Notepad++ and looked at the RTF codes. I don't completely understand RTF syntax but I can look at the chapter headers that split and the ones that didn't and they _look_ the same.
