I have finally managed to fix all the issues with the DLL and it now produces bit identical results to oggenc and oggdrop. The Pre 10 version will be available at: http://www.inf.ufpr.br/~rja00/ , as usual whenever Roberto updates his page next. If any is really desperate, private message me and I'll mail it to you.
PLEASE NOTE: If the top level bitrate goes above 350kbps, it may be necessary to make a small change, basically to increase the size of the internal output buffer.
Enjoy!! and a Happy Christmas to all the other sad people who have nothing better to do on Chrismtas day than browse their favourite board!!
