Hi,

I tracked it down in my case. We are hosting on a Windows platform. The problem appears to be in the building of the URL for the podcast: private function determineURL($filename). It is using the DS (DIRECTORY_SEPARATOR) in the URL just prior to appending the file name:
$filename = JURI::base() . $mediapath . DS . $filename;

Windows uses '\' for DS, but not in URL's; so, I think this is where the problem is. It should probably just use the '/'.

Thoughts?
