mp3 files not mapping correctly with FeedAPI and Feed Element Mapper

Hello

For some reason when I map the relevant fields nothing displays on the actual view / node for that RSS feed. I have followed very good tutorial (http://www.drupaltherapy.com/feedapi) but this does not work for me. Firstly, the tutorial is for embedded video, and I am trying embeded audio but it still does not work. It seems that not all the fields from the RSS feed are being pulled in and I cannot drill down to the relevant field for the mp3 file.

Any advice?

Thanks
