Thanks for getting back to me so quickly. Yes, in fact I downloaded Switch last night. It looks like I'm getting the message "....copy-protected by Digital Rights Management (DRM)" and when I look under the properties->license it says protected. I guess I'll just have to try other songs.
What about .cda music files....I get a codec error. Do I need to download the drivers you specified in the link?
Thanks for all your help. I'm trying to put background music to a slide show.
