Hmm. IIRC there was a bug between older oggenc and the new bitrate 
management stuff in libvorbisenc, where kbps was being read as bps.
That might explain the problem. You might see if you have the latest
release of both libvorbis and vorbis-tools and/or try -m 96000 -M 225
and see if that gives the old behavior (if so, you should definitely 
upgrade.)

HTH,
