I recently transferred a load of tracks to my NW-HD3 but don't seem to be able to transfer them back to my PC. Is this right? - A real pain as I deleted them off my PC thinking I could get them back from the device. Also I would prefer to use MP3 on the basis I could move everything across to another player if I am unhappy with Sony. I notice the sound quality on ATRAC3 256 is much better than MP3 256 - is this most peoples experience? Thanks! Joe.
