Loading an FLV into FMS using a URL Var??

I have a rather large inventory of user-supplied videos. Our visitors upload their videos to our server and an ASP script sends them to a com service and encodes them as FLVs. At the same time a database entry is made from the submission and a filename is generated and entered. A separate app serves up the videos based on search criteria - dynamically from the database via a Cold Fusion server (it pulls the filename out and inserts it dynamically into the URL, when the user clicks on the file, the SWF loads the file).

Here's a link to the app that's live right now;

Everything works great except it's progressively played and we wish to switch to streaming format.

I'd like to keep the coding to a minimum and maintain my Coldfusion application which works extremely well. Is there a way I can subsitute the addressing from the http:// address to the rtmp:// address? In other words, all I wish to do is to modify the url to use rtmp:// and stream rather than download progressively.

I am not versed in actionscript, but I imagine there is a way I can create the SWF FLV player with the netstream stuff in it, and pull the FLV name from a URL parameter. Correct? If so, how do I do this?

Thanks
