I got my Sony DVP-CX875P on weekend and try to play Mp3 files randomly (shuffle play), however I could not do it. Is this player does not play Mp3 files randomly? There is no option to select. If I select ‘one disc’ option then shuffle play icon has only ‘OFF’ and there is no any other option to select. If I select ‘All discs’ then shuffle play icon has ‘DISC’, but there is no any other option. Thanks.
