Hi I have a movie clip which is exactly W: 1100 H: 750

All i need is to add is mouse movement so when you scroll up down left right the movie clip moves about 50pixels in each direction.....any tutorial script I have found does not add a width and height restriction making me drag the movie off the screen. I've seen this a lot in websites so thought it would be simple enough to find but I haven't been lucky so any help/tutorial link etc will be great
