Not really. I've had the same problem with both Icecast streams and Mp3s
encoded with LAME. It might be a number of things, including:
* Mp3's 100hz bug (As was the problem with the ISO code and
Winamp)
* mpg123 bug
* LAME bug
Try encoding static files on the same encoder your using at the same
bitrate and try them. I'm thinking it's an ISO Mp3 bug, not a problem
with LAME or mpg123. (I forget the flag to enforce ISO conformance, but I
know it doesn't work with liveice properly or ices the last time I tried)
This was one of the main reasons why I switched from using mp3 to
Ogg Vorbis (even though I still have to maintain the station's Icecast
1.3.X server at UNBC when I get back).
