Thanks, that's one question down!Sony DAPS don't resample with the native Walkman Player, but all other apps are resampled to either 16/48 or 32/192 depending on the High-Res streaming setting.
I don't think I worded my other ones well.
1) I think Walkman Player will read m3u playlist files stored in the MUSIC/ folder root, but does anyone know if these are then editable - I can add further songs to the playlists they store?
2) If so, can these edited playlists be exported back to a Windows music player, presumably Sony Music Center if that thing is still going?
