I just got my NETMD (MZ-N420D) today, and have upgraded the Sonicstage software to version 2.3. I am now transferring the files from my CD's to 'My Library'. I am trying to set the 'Format/Bit Rate' to MP3. According to the help, this should be possible, but it also mentions that: 'Note "MP3 (MPEG1 Audio Layer 3)" cannot be selected unless "SonicStage MP3 Add-on Program" is installed on your computer. Where do I get this add-on? Thanks. Rino
