Another Reversing question

Hi everyone,

Im super new around these parts and must apologize for asking questions so soon, but i have hunted around the internet all yesterday and got no were. Im also very new to this AS3 stuff. Onto my question, I would like to reverse my timeline sounds simple enough but i would like it to recognize stops or something:

I have a movie clip (MC_slider) with images that scroll through in 10 frame intervals which use’s stop(); to stop it. On the main stage I have 2 buttons. 1 button (BTN_next) when clicked plays the movie clip until its next stop. Button 2 (BTN_prev) this is the button on click i would like to play the timeline in reverse frame by frame until it reaches its previous stop(); which would be 10 frames.

http://www.onlinearts.net/Article18.htm Ive been looking at this but its all AS2 and i dont know how to convert it to AS3.

Any help or links would be greatly appreciated thankyou. As a side note i tried posting this over at actionscript.org and it lead me to here so i thought why not ask the source.
