For those of you who have the new series, are the chapters customized to fit the actual sections, e.g., cardio vs. toning? I have checked 2 of the 5 DVDs in my set, but the chapters there were every 5 minutes on the dot, which didn't correspond to the actual breakpoints in the workout. I find that annoying and disappointing. I'm hoping mine are defective and that they're actually supposed to be properly chaptered!
