Comment 1 for bug 83074

It looks like you don't have mp3 support installed. A lot of streams are in mp3 format, so make sure you've got that working: https://help.ubuntu.com/community/RestrictedFormats

The multiple entries in the playlist for some streams are because that stream has more than one mirror, in case one goes down.

Let me know if it's still not working after you've got mp3 support working.
