An ACM driver will not work in MediaPlayer, because it doesn't recognize the
ogg files. Instead you need a "stream handler" filter for parsing ogg files.

To see what I mean, you can try
ftp://zorannt.sourceforge.net/pub/zorannt/Binaries/Codecs-20010501-Binary.zip

The sources are on the FTP server and in the CVS at
http://sourceforge.net/cvs/?group_id=24067

This is only a snapshot. If you use the MS GraphEdt application, keep in mind
that the filters are only "half" implemented. Only the "OggDemultiplexer",
"VorbisFile" and "VorbisDecompressor" filters work (at least partially), while
the property sheet handler and the "VorbisCompressor" do not yet.

Btw: If someone can tell me why Windows Media Player doesn't stop at the end of
a file, please drop me a note.

Regards Ingo
