My ISP, bless their little cotton socks, passes multicast traffic which includes a number of BBC streams - Radio3 realaudio encoded at 132k sounds much better than the usual 32/44k I got before. However, mplayer doesn't appear to like multicast streams, anyone know how to get it to work (assuming its possible).

I don't have an answer but can tell you I see the same error. If you do get this working the "resample=44100" part of the command line drops the stream down to 44.1k and I don't know what the maximum rate the squeezebox could receive.
