The players look at the filename to determine whether a single file or
a playlist is loaded. For example, if your file is test.mp3, it will
presume you load a single MP3 file, because the extension is "mp3". If
your filename is getlist.php, the SWF will see a playlist. If you use
dynamic scripts to load a single file (e.g. getmovie.php%3Fid%3D123),
you can tell the player which file it loads by using the additional
"type" flashvar: "type=flv".

I'd like to point out two common pitfalls users encounter when using
playlists. First, a playlist should always reside on the same server
as the SWF file, due to security restrictions of the Flash Player
(there is a small workaround, tunneling the external feed through a
serverside script. Here's an example in PHP.). Second, always try to
use full URL's (including the http:// part) when referring to files,
links or images in your playlists. It will save you a lot of troubles
with unresponsive SWF's or "file not found" errors!

So don't think passing playlist URLs to remove sites will work, unless
via a proxy script.
