LOL! Same thing here as well: how to copy analog-recorded audio from net-MD to PC (checking-in...?) My model is a mz-n710 (the european version... ) and I've read the manual thousands of times, and no sign of checkin-in at all!!! All I can find is info about checking-out: tranferring data (MP3 ie) from PC to net-MD thru usb. Now can somebody tell me: is there a way to get transfer dj-sets, analog recorded with my precious mz-n710, on my PC thru the usb connection??? Is it possible at all? Does this mean I need to "modify" the firmware ? Or do I need to find the right software... ' Hope we'll find out soon... Ape is in a tree!!!
