  Just to verify your results, the only two of the streams above which I
  can play are the last two. The rest of them give me xruns of varying
  length with ALSA, and dead silence with OSS output.

  This is kind of strange, I can't tell whether it's an issue with the
  decoding or if it's in the stream transport itself. 

  Anyway, FWIW, it's also broken for me (except the last 2).
