I have it working with Winamp now. Though, everything is very squeeky. Winamp says it's playing at ~ 94 kb/s, which is faster than what your server says it is streaming. Could this be causing that?
It won't be helping. I've had this problem using edcast with the shoutcast DNAS server. Trying to balance off this problem and fix it or tackle the compatibility issues with Icecast, which does stream in the right bitrates.
I never got the chance to test the old setup with Winamp, since it was updated before winamp testing and after my testing with VLC. So I'm not sure about compatibility with winamp before, at least on my end.
