Hello,
I know of course that spaces in URL is a bad thing, but not all of my contributors know it...
I don't know how Flash or Javascript hadle these links, but with a real podcast software (It****), it seems to work.
I just posted this trick because everything is not perfect in a perfect world. I also don't have the authority to rename files on the podcast server, it's just a quick patch for those who are in the same situation.
