add the radio to streamtuner

i am install streamtuner in my PC,think to add the channel from  msn-radiohttp://radio.msn.com/default.aspx?it=15i don't know how to add it,thanks in advance!

i must install the gnome,if i install the xgl

I uses the window maker,but i saw  a lot the document about xgl,said you  must install gnome-environment before install xgl, it's really?:)
