Flash playlist with PHP?

I would like to know if its possible to play Flash movies back to back without refreshing a browser window.

Basically I have various Flash movies (been generated by another group of developers) that need to be played in sequence without any external interaction. These developers would like to be able to make on the fly changes to the content.

My first thought was to load a browser instance and use js to spawn a fullscreen window if one wasnt already present. The parent window refreshes every 2 mins, if the child window exists and the playlist content has been changed on the server, then the javascript refreshes the child.

The child loads the first movie of the playlist. At this point im at a loss as to how to continue, can I use a javascript event to test when the movie finishes? in which case i can simply write the movie variable to a form as been played and submit that form, or can I have the flash developer make the flash fire off a javascript function or reload the page posting its own name as a variable? or is there a simpler alternative that ive missed altogether?

Any help would be much appreciated.
