There is a range where the highest % of fat will be burned in relation to the total amount of calories burned. But if you look at total amount of calories burned from fat, then the whole fat burning zone becomes obliterated. It's just that at higher intensities you will burn a lot of carbs in addition to fat.
You mean those machines with the scales and in the middle it has the "fat burner" range for age?
My understanding is that cardio burns muscles more so than fat. Ideally, you'll want to max it at 60-65% which is above the "fat burner" range, but yet the problem with that is you're working pretty hard and losing muscle as well as fat.
The assumption, which is false I believe or at least not proven, is that if you're in the 40%-50% range, you'll burn more fat since you're not working your muscles as hard. I forgot the whole detail of it and it's been a while. I'm pretty positive Karky has it right.

ACE just had something about this in one of their newsletters. Maybe this will be helpful to you....
Normal sessions of cardio do not 'burn muscle'.
The issue with very high intensity cardio is that it starts to become an anaerobic exercise...and without oxygen (aerobic exercise) the body cannot burn fat for energy.
Muscle glycogen is the other primary source of energy for cardio. glycogen is essentially stored carbohydrates. You use glycogen during your resistance training...and is the reason many PWO shakes suggest simple, fast digesting carbs like dextrose...to replenish glycogen.
