Chapters on iMovie 10.0

Hy there.

I'm kind of a new user on iMovie and on iDVD so I don't know if someone can help me.

I've got this movie that i made for a wedding that has 1h and I need to make a dvd to give tho the friends. I have updated iMovie to 10.0 and I need to create chapters so in iDVD could be seen as a hole movie but with chapters, so that I don't need to cut the in chapters and also put the hole movie.

Can anione help me with this?

Thanks...
