Have just got my NW-HD1 back from Sony with 'MP3' upgrade Comes with sonicstage 2.3 which does not appear to offer 'MP3' as a recording option amongst the ATRAC options on the options menu. The help file says ensure that Sonicstage MP3 Add-on is installed. 'Add-on installing' did appear during the setup so I assume it has installed. I have tried several re-installs but no luck. Getting 'rather fed up' with Sonicstage anyone out there had success with MP3 on the HD1?
