OK - here's a strange one.
I have 5 Soundbridge's. The M1000 in my bedroom will not play WNYC-FM (an mp3 stream) or Wonderground Radio (a windows stream). Both stations are saved as favorites. Oddly, it will play WNYC-AM (also a mp3 stream).
The other 4 SB's (2 M500's, a M1001, and another M1000) all play these streams just fine. The M1000 in the bedroom is running the latest beta, but I don't think that's the problem because another M1000 (also running the latest beta) plays both streams.
Thanks for the help.
