Update:
It seems to be a 2.3.3+ only issue. I downgraded to 2.3.2, and it worked just fine. The developers need to get on this immediately if I have to update.
Currently I host a radio server using Icecast 2.3.3 (2.4 broke a few things for me).
I have a fallback mount of /live.mp3 that is /stream.mp3 (which is the Auto DJ), but I'm having some issues.
