Speaking of specific segments yahoo, I think for me, I can have an opinion today and then it changes when I decide to revisit them. Sometimes the dance section of happy hormones feels real good to me, but some other days I program that segment for my workout and it just doesn't jive great with me so I skip it.
Same thing happened to me with the second set of the original beginners and beyond DVD - the first time I did it I hated it, but I did it a few weeks back and it felt much better... good even. My advice is to pick your DVDs one by one and "explore" one at a time - Like Pat says, you do your tune in, a warm up, a set and then your deep relaxation or a meditation, choosing a different segment when available (warm up 1 one day, warm up 2 the other... something along those likes) I've been doing this and taking notes afterwards and it's been working for me
