I don't know how to edit sound tracks downloaded from CD's when I don't need the whole piece of music. Any ideas? I want to 'crop' soundtracks I guess! Also when I purchase music on the net it shows as 'protected' and can't be dragged into slide shows for the audio track. Any one know if this 'protected' command can be removed? I realise copyright issues are at stake. Thanks, David
