Hi, this is my first post, having found the forum due to an annoying problem! I have roughly 1600 mp3s stored on my hard drive - all via iTunes (Windows XP) - all at 192kbps, 44.1 sample rate and not variable bit rate. I have SonicStage 2.0 installed and a Sony MZ-N710 NetMD. I am trying to do my first compilation mini disc in LP2 (132kbps), however, when I try to convert the tracks to Atrac I get the message saying that "SonicStage does not support the file format of the track." According to the help file included with the software it should! Am I doing something wrong here? Please help! Cheers, Mike
