How to manage media bookmarks?
 

I just got an N800 and have added several radio stations to the media player's bookmarks. However, how do I get rid of some of the pre-installed media bookmarks that I do not want? In other words, how do I manage the media bookmarks? The media player does not seem to have management access to the menu of stations on the desktop application.
I appreciate any suggestions.
Best,
H.
