Firefox workaround!
I haven't been through every post, there's a lot of pointless posts, but I found that using Media Player 10 and Firefox 1 (latest of each)
you will most likely see connecting... right away even before selecting a station, hit the play this station button to start a stream (within 6 or so secs) (though I have altered the RADIO template to include the controls, which firefox plugin doesn't ignore.
once you start streaming the first channel in the list, you can then select any channel at will with good ol' Firefox.
Apologies if this has been mentioned already, but this hack thread is getting cluttered quick
Great Hack
