I don’t know what Cover Flow is but this basically looks an image slideshow. I think it will load only SWF, JPG, GIF, or PNG files.
FYI: This is MC_Tween:

You need to install it first, follow the directions here:
http://hosted.zeh.com.br/mctween/downloads.html
Once you have it installed, all you need to do is add the following to the top of your actionscript
#include "mc_tween2.as"
Then you can call any of the MC Tween functions like this:
movieClip.slideTo(x, y, seconds, "linear", delay);
Replace the following
movieClip: this is the instance name of your movieclip on the stage
x: the x coordinate where you want to move to
y: the y coordinate where you want to move to
seconds: the time in seconds in which you want this to happen
linear: there are several differnt animation types
delay: the time in seconds you want to set as a delay
There is also the Class called tweener that pretty much replaces MC_Tween.
