I have got a NET MD MZ N-707. The blue one. MDLP mode. I want to transfer my recorded sounds (it recorded in Atrac mode) to my PC. I know that only Hi MD's can do that right? BUT I managed to do it from the headphones out to the mic in or line in of my Pc in realtime. My Questions are : 1 - What is the sound quality difference between optical transfer and USB transfer? Is it just a time difference? 2 - If I use the headphones out of my MD goin to the optical in of my PC, would the sound quality be good as USB? 3 - My MD had an optical IN but no optical OUT, but still, is it possible to use my MD's optical IN, in order to transfer songs from my MD to my PC? 4 - Is it easy to transfer files from MD to PC with a Hi-MD machine? Without any software issues?
