Hi everyone, I just bought a NW-S706F and can't seem to transfer mp3s to it. They're continually converted to ATRAC, despite me setting the option to leave as original format. What gives? Do you HAVE to use the SonicStage (came with 4.2, I have 4.3) software to transfer files? I've looked at the file structure on the player (which is how I know the files are in Atrac format, "OMA" extension, plus they differ when compared with a Hex Editor to the original mp3 files, and realise it has an internal database, has the music. I was hoping I could just transfer mp3s straight to the player, from Windows Explorer, and they work straight away, rather than take a long time to convert to Atrac, just to play them. Hope this doesn't sound like a whinge, just surprised Sony would make such a nice player, but have such terrible software (SonicStage) to go with it. Thanks, Richard.
