Replying to Tricks in DVD's

alright tell me if you think this is a good idea. Personnaly im new to new school skiing and havent learned what every trick is, but id like to know. ive seen a lot of movies though but they really dont help if you cant identify tricks. So what if dvd's came with an optional obility to see what each trick is while the pro does it? That way new guys can learn the tricks and veterans dont have to deal with. Like it could be something you turn off and on at your choosing. Is this a good idea or just to much extra work?
