i got my MZ-S1 from my cousin and he didnt gave me the USB and software, but i download the software and bought a new USB mini B cable, when i was recording with sonicstage, its seems like recording but, when i play the MD there was no sound and when i turned the player off, the player displays a message blankdisc, so i thought it was a software problem, but when i tried recording using an optic cable from a friend, the same thing happen, during recording realtime i can hear the music playing, and it shows that it is recording, but when i turn off the player and turn it back on the player still display a blankdisc, but it can still play MD that i borrowed from my friend, can anybody pls help me, thanks in advance...
