firewall must be configured in the way
 block all , except ( ports that you need ) , in that way you narrow down "problematic ports"

most of stream radio station use port 80,
 you can monitor traffic, and add IP address of stream radio's to deny access list

i don't know how mandriva work's but i belive that you can add proxy or some sort of add-on for that purpose ( url-filter or something )

You could simply create an account with OpenDNS, set your DNS statically to use their servers, and create a rule to block streaming audio/video.  If you don't have a static IP, you will need to download their dynamic IP client (also free).

Forgot to add...w/ OpenDNS, you also have the ability to filter objectionable content.  The fee based version allows you to setup groups for varying levels of access.
