Favorite Workout DVD

What is everyones favorite workout DVD? I use my ellipitcal machine when it is cold during the winter. I am looking to change it up since I had a decline in my FEV 1 47%.. yikes. I am not having any symptoms of an exacerbation, very strange. My doctor suggested doing hardcore cardio to get my lungs into shape.

Any suggestions of a good intense cardio workout DvD??

Thanks,
