iDVD problems

Heyy fellow Fiction Field-ers! So I'm having a problem with my iDVD. After I export my file as a quicktime off Final Cut Express and drag it into iDVD it goes through all the steps but when it gets to one of the last steps it ejects the dvd. The problem is there are still steps to go when it ejects the dvd so it never fully finalizes. So frustrating! Has anyone ever had the same problem?
