[vorbis] Streaming content from BBC just stops

Neither, it's icecast.

There's a server side client queue.  Each 'block' is equivalent to an
Ogg page currently.  If you are behind 10 blocks, you'll get dumped.
That's about a 40k buffer.  This is a 'magic' number.  Perhaps it needs
tweaking.  But I suspect in this case it would have just taken slightly
longer, even if the queue was bigger.  If you were listening fine most
of the time, and getting cut off now and then, it would be a different
story.

Sounds like an xmms feature request :)

The queue is there to prevent that.  Without QoS there's really not much
you could do in the general case.

This feedback is good, but in this case I think xmms is not doing what
it should (reconnecting or signalling a disconnect or both) and that the
real problem is that the pipe wasn't big enough.
