Any yoga (that I can do with dvd) that burns calories??

I have been sticking to elliptical and weights which is great accept my buldgind disk is starting to give me issues again. My hamstrings have even become so tight that I can't even straighten my leg all the way, let alone stretch it back. A year and a half ago when all this started, the physical therapist suggested I stop doing cardio and weights all together and dedicate myself to yoga. She said the disk was buldging, the muscled in my back, hip and all down my leg lacked any mobility and I have arthritis in my back and hip. I tried doing Bryan Kest's power yoga, but since I also have quite a bit of weight to lose, I noticed the scale stopped budging. I continued backing off the cardio and just stretching and doing yoga but then that's when I noticed I was actually gaining weight (from lack of any real calorie burn I guess). Does anyone know of any kind of good yoga/pilates based workout dvd's that burn about as many calories as cardio????
