R – How to control flv embedded video using external buttons

I am not new to Flash but I have not properly used it for sometime, a lot has changed and as such i am unable to figure this out.

I have embedded a flv video into my timeline, it uses the flv playback component to play and the SteelExternalAll.swf skin. I would like to control this flv using buttons that I have created that are postioned next to the video player. Ideally, these buttons would be thumbnails, similar to chapter thumbnails on DVDs and would serve a very similar function. As these thumbnail buttons are always present, I want them to change while the movie plays, I think a border around the currently playing would suffice.

The video is nearly 3 mins long, I have made cue points from Sorenson Squeeze.

What is the best way to do this?

Many thanks in advance
