how to use chapter markers in imovie

When I make a movie in i-movie with "chapter markers" and then transfer it over to i-tunes to play on my i-pod touch. The titles can be seen on my i-tunes but not on my i-pod touch ver 2, I can see the chapter markers but then are all "Chapter 1, Chapter 2 etc...not what I named them. They can be seen on my original i-pod touch. So what am i doing wrong with how i am making the movie or how I am playing/transfering them.
