Gene, any chance you can run the same experiment but with a wired 
network connection and not a laptop?  My workstation plays music just 
fine but my laptop behaves as you described when using either a wireless 
LAN connection or a hardwire.  The laptop plays music from either the 
hard disk or from a network share (NFS over wireless) without a problem 
but any attempt to listen to internet radio on it is pretty hopeless.  
The laptop should have more than enough resources (1GB ram, Athlon64 
2200+ CPU) but all I see are "congestion" warnings and what little sound 
I get is all stuttery.
