Hi, I just received my MZ-RH10. I uploaded some tracks (MP3&AC3) to the MD using the SonicStage software. But I just can't edit track titles using the recorder. First I select a track, then I go to menu > Edit > Title Input > Track. And when I press enter, I get the message "CANNOT EDIT". Why is this happening? This happens to both mp3 and ac3 files. The 1GB Hi-MD disc is not locked either. I searched the forum for answers, I read the manual over and over, but I just can't get this working. Am I doing something wrong? Using SS to edit titles work fine, but sometime I want to use the MD to edit track titles, this really bugs me. Any help appreciated.
