The trick, aside from having a background that tiles seamlessly, is to have 

an extra margin above (or below -- your choice) and to one side, in which 

the image starts to repeat. The margins must be as high or wide as the 

movie dimension, so that when the image has fully scrolled, the visible 

portion is identical to what is seen at the other extreme of the scroll. 

Then you would place it in a movie clip so it loops from one extreme to the 

other. you will need some action scripting to keep the X or Y the same when 

looping, depending whether the scroll is horizontal or vertical.
