Change source of flash video


I am building a presentation DVD for a museum, and they want it to be like a website, with videos and stuff.
The video-player should be made in flash with a FLV component.
Since there is a lot of videos, it would be nice if I could embed the player and somewhere (in the HTML) place the link or reference to the video that should be loaded… How is that possible? I have read something about FlashVars and stuff, but I cant figure it out:hair: Especially the Flash side of things were should the variables be placed?

It would be nice if you could come with an example

Thanks in advance
