Funkdeal: I assume you are using the aoTuV CLI encoders? IIRC aoTuV CLI encoders are named oggenc
2.exe.
Have you renamed the file to oggenc.exe? Thus the configuration as shown by the page you referred to will work.
Alternatively, change the configuration to oggenc2.exe instead of oggenc.exe.
I suggest you download from
the rarewares site. And if you have
the need for speed, check out Lancer suite
in this site.
OT: LOL, for MP3, the page went good -> very good -> very good -> best. For Vorbis it went very good -> extreme good -> fantastic
Edit: minor typo, add links to rw and lancer
