Thank you very much Syrius! SonicStage does play Hi-MD content back through the PC. I am lucky. This also explains why it takes so long for SonicStage to transfer the PCM audio from Hi-MD to PC. I think it's scrambling the signals back to the disc during the transfer. See SONY. DRM's cracked with the help of your own SonicStage. Come on, drop DRM for analog recorded materials, at least. Now, I have to find Total Recorder and Audacity and learn how to use them. Many thanks.
