Podcast - Rename file

Hi,
I'm playing podcast radio show with Subsonic but the stream is not well configured : each episode had the same filename.
After 2 days, I don't know witch is the last episode.
I'll appreciate an automatic file renaming with the day of download and hour (20101013_073000_$filename)
Or because this feature is maybe useful only for me, if you can help me to auto-parse the XML stream to rename the filename before Subsonic download the file...
Thank you,
Olivier
