Random (sequential) Movie Clips

I have to create a homepage where several movie clips play in random order, one after another. The client wants a different clip to play on each page refresh, so users see a different swf each time they come to the site. (It is a stock photo site, and each movie clip is a text/image combination) The swfs are each only a few seconds long, and when one is over I need it to play another one. I have tried arrays and several other tutorials, and I can either have it play at random but repeat the same swf, or it will play the array but not at random. Any suggestions? I am using Flash 8 Pro. Also, the client wants the page size to remain small, which is why there is a master movie clip which the swfs load into. Please help!
