[icecast] Transcoding from icecast2->icecast2 results in "garbage"

I don't get what you mean. My problem is that I'm streaming over a 
DSL-line and have just max 128kbit/s upstream. What I want to do is 
use a 112kbit/s-stream for the "high-bandwidth-users" and transcode 
the same audio to mono (e.g. 40kbit/s) on the server for "modem-
users". That's my problem. All with Oddcast DSPv2, Icecast2 and MP3 
everywhere (since my users can't handle ogg-streams).

So Oddsock, what did you mean?
