[swfmill] WARNING: this file is not a valid MP3

Thanks for your help, Mark. I can't really test if Flash 9 will play mp3s
with other sampling rates, because swfmill gives me an error if I, say, try
to use an mp3 with half the sampling rate.:
   WARNING: this file is not a valid MP3
   xmlXPathCompiledEval: evaluation failed

Does anyone know for sure if Flash 9 supports mp3 sampling rates other than
44100Hz? If this is the case, it seems like the swfmill source could be
modified to support this option. Thanks.
