JW FLV Streamer breaks for files nested in subdirectories

I have a streaming setup something like this:

Streamer url: rtmp://streaming.myserver.com/_streamer/
Stream: subfolder/my_stream.flv (or my_stream.mp3)

The wijering4_swftools_flashvars(...) hook inside of wijering4/wijering4.module strips out subfolder and tries to stream only my_stream.flv. This, of course, breaks, because there is no stream by that name in the root folder. I got my stream working by commenting out the line

$vars->othervars['file_url'] = $info['basename'];

It would be great if the next release of SWFTools included this by default so my code doesn't break when I upgrade the module.

Thanks!
