Using amarok to listen to podcasts...

[icoupal]

I'm having issues using amarok.
I've successfully used it to listen to some podcast.
But when attempting to list to the nature podcast,
I get an error saying it doesn't have a codec to play the
podcast. Looked at some other threads and tried suggestions like
ubuntu-retricted
libxine-etracoedcs
etc..

Still nothing.
Any help would be greatly appreciated.

Thanks
