Okay, I've built a libvorbis package using
http://svn.xiph.org/branches/vorbis-tahseen,
however when I run ogg123 on my test files
(with interleaved Vorbis and non-Vorbis pages),
I still get
"=== Vorbis library reported a stream error."
coming up every time it crosses a non-Vorbis,
with the corresponding clicks, XMMS behaves
the same way too.  I'm pretty sure that I am
actually using the Tahseen library.  Is this
the kind of case it's meant to handle?  If
so I'll have a further look at what's going
wrong.
