Lala1, that happens to me too if I push the "next" button too quickly, but only with the newer workouts like Xtrain. But if I push a second time after getting the "operation currently prohibited" message, I'm able to skip over those initial chapters. One of the things I've always appreciated about Cathe's DVDs is that you don't have to waste your time watching warnings and introductions over and over again!
