I was a bit confused by that statement as well Lee. I've done a bit of work
with mp3PRO using a source developed from scratch and a version of the
original Icecast modified only trivially to deal with specific metadata
requirements.
There is a very high level explanation of mp3PRO at the
http://www.mp3prozone.com/basics.htm site. At the risk of being somewhat
incomplete i will add:
1) The "normal" frames in an mp3PRO file can be decoded by ordinary
mpeg/mp3
code. The SBR frames will simply be thrown away. An mp3PRO file reports a
sample rate in the non-SBR frames that reflects only those non-SBR frames
and thus timing is not effected when an ordinary mp3 decoder throws them
away.
2) At low bit rates and up to about 128kbps mp3PRO files and streams in
general sound amazing when compared to mp3 files encoded at much higher bit
rates. Above 128kbps you do not get much benefit using mp3PRO, but to be
fair it was designed specifically to deal with high frequency loss at low
bit rates.
John, i could not say if the problem is in Icecast2 or in the source you are
using. One of the Icecast2 developers might be able to answer that after you
provide a more complete description of your setup. In the meantime however
it would be fairly trivial to setup a test to isolate the problem using an
old version of Icecast (not Icecast2) or another streaming server such the
one found in Apple's Darwin project.
Best of luck,
~ Chris

If when you say "the other OS" you mean Windows, there are a plentiful
amount of ogg vorbis source clients for Windows. A very popular one is
the oddcast plugin for Winamp. If when you say "the other OS" you mean
MacOS 9/X your options are much more limited.

P.S. MP3pro isn't mpeg? What't that about?
