inserts for ogg are different to mp3. It is generally better to get the
source client to do that as it will be in sync with the content.

from here, ogg123 is ok (although a 128k buffer, not sure what the
prebuffer % is, seems to be low, try increasing those). mplayer is fine
but vlc keeps resetting itself in a major way on a new logical stream.
The format of the stream looks ok, I don't see any specific issue with
it. There is one other thing I can check but I'll have to get back to
you on that.
