best wkout DVD for beginners

Hi everyone,
been surfing the mess bds, and am confused by all the choices.
is there an easy to harder progression of JM's dvds, including the new BR?
how does JM compare to Turbo Jam? I tried Turbo fire in the summer, but it really bothered my knees
anyone have good shoe reccs for indoor dvd workouts?
thanks,
looking for fitness in 2013!
