Unity Webplayer StreamingAssetsPath = Raw?

I'm trying to stream a video in the Unity web player. I'm using the following code to fetch it:

             string path = Application.streamingAssetsPath + "/" + video;
             if (!path.Contains("://")) path = "file://" + path;
             WWW www = new WWW(path);
             MovieTexture texture = www.movie;

This works fine on the standalone player. However, on the web player, the path will be something like

 file:///C:/Path/To/Deploy/Raw/trainToBeirut.ogv

Note the "Raw" in the file path. In reality Unity puts the video file at

 file:///C:/Path/To/Deploy/StreamingAssets/trainToBeirut.ogv

In fact if I reaname StreamingAssets to Raw everything works fine. But that seems silly. Why is Unity wrong about the StreamingAssetsPath? How can I fix it short of renaming the folder or doing a needless conditional?
