hi there! i have a MZ-S1 unit, and i use sonicstage 3.3. for some odd reason, i have background noise when i import music lately. it happens only on certain files, regardless of the bitrate of the original mp3; it happens even if i change the media, and the weirdest thing- it DOESNT happen if i use simpleburner, or if i first burn the mp3 to a cd and THEN import from it (with sonicstage). does anybody here have any experience with such a thing? the situation is becoming... well, unbearable... thanks
