From author's own website: "I lost interest. I didn't use the application myself."
After hunting around, I recommend anyone looking for properly tagged Lame encoded MP3's use iTunes-Lame Encoder (now on Google code and open source after Alcor also lost interest).
I have also used/tested Audion (PPC only, also dead) and Max (great encoder, lousy tagging) and XLD-GUI (absolutely toxic).
