Charlie Brooks Exercise DVD - How many Calories lost?

Hi

I've just done Charlie Brooks exercise DVD but I've no idea how many calories I've just burnt lol.

The DVD is made up of five 10 minute sections:

Warm-Up:
Hip circles, squats, shoulder rolls, side steps, punches, marching, heel digs, twists, cha cha steps, lunges

Disco:
Marching, side steps, hip rolls, cha cha steps, wide marching, knee lifts, twists, heel digs,

Combat:
Punches, hooks, sway and duck, knee lifts, kicks

High Intesity:
Marching, wide squats, side steps, pony, calf raises, lunges, skipping, jogging, sumo squats, star jumps

Pilates Cool Down:
Stretches, press ups, plank, stomach work

Does anyone have any idea or a rough estimate as to what I would have burnt?
