I used Hypnobabies for a natural childbirth almost two years ago and highly recomment it. It helped me sleep well throughout my pregnancy and stay focused during labor - people who watched me labor commented on how relaxed and in tune I was with my body. It didn't make labor painless or lessen the intensity of the contractions, but I never felt out of control or helpless even during transition.
I also found that the hypnobabies tracks were so helpful for my anxiety that I would use them on plane flights (total nervous flier here!) and for pain management/relaxation when I had a bad headache and just wanted to sleep.
