Hi. I'm about to purchase a Sony mz-rh10 (Hi-MD). I'll be recording with a mic (AT822) and need to get a wav file onto my PC. I hear horror stories about Sonic Stage! Questions: - Can I just transfer it via the usb cable? - Do I need the Sonic Stage software if I'll never transfer files FROM the PC TO the minidisc? - What's the difference between a pcm file and a wav file? Thanks for your help, David
