First of all, it's Blu-ray, not Blue-ray.
Second, it does not offer higher frame rates. In fact, the reason that it offers "better motion depiction" is due to its lower frame rate. Blu-rays can do 24 frames a second which is the same frame rate as film. DVDs do 30 frames a second (after being de-interlaced), so the film's 24 fps needs to be converted to 30 fps (actually, 29.97 fps).
See the wikipedia article on Telecine to learn about the conversion process.
