Thanks for the quick reply. I have the PC Link which connects my MD to the USB port. Is this what you are talking about when you mention the digital(line/optical) input? If so my computer, when I use the SonicStage software does not seem to recognize this link and defaults automatically to the CD drive in order to transfer the songs. Sorry for sounding like such a dolt but haven't use the MD for three years and now that I am missing all the installation software I forgot how the darn thing is supposed to operate.
