Here's why I wonder if I can upload from a non-Hi MD disk from an RH-10 via the usb cable QUICKLY...it's a quote from a message sent to me: "Be aware that Hi-MD's are not that easy to come by - you'd probably be better off buying a stack of MD's to begin with, unless you plan to record long stretches of sound in PCM. You can also record in ATRAC3plus (the codec Sony uses in MD/Hi-MD), and convert it to WAV in Sonicstage once you have uploaded it. The resultant sound is not 'CD perfect' but is still a darn sight better than WAV recorded on a camera."
