using articulate in a rails project

[eight]

I don't know how many of you use ruby on rails but I am trying to use some articulate generated swfs in a project of mine.
I am not using the generated player.html file but have my own .html.erb file that loads the playershell.swf. This swf file is loading fine but then nothing happens. From the activity window in Safari I'm finding 2 errors.

http://localhost:3000/presentation/slidegroup.swf not found
http://localhost:3000/presentation/stealthray.swf not found

So, it looks like it's trying to follow the URL in the address bar to get the other files instead of just looking in the directory the swf is located. This won't work with rails since the shown urls don't correspond to actual directories but rather to Rails controllers and methods.

Can anyone help me out with this? I really expected that the playershell.swf would just look for the other files without a path, assuming they were in the same directory.
