Problem "moving/sliding" Movie Clip

I have a large movie clip which sits on top of the stage which resembles a wall with photographs on it.

It is much larger than the stage so only a section of it is viewable at any time.

I would like to be able to smoothly move/slide it to specific locations (by coordinates) with a button click so that a specific area is shown.

I cannont find anything after searching which would allow me to do this smoothly (rather than just a solid jump to the new location.

Any ideas/hints/tutorials?

Thanks a lot,
