Hi, Dory!
"Music CD's" usually refers to regular CD audio like you use in a normal CD player. This does not mean it has to contain music. Even an audio book purchased on a commercial CD is in CDA format.
Daisy books have audio files in them. These audio files are in either MP3 or WAV format. You can play these files with your computer like any other audio file of these formats, but it might not play in the proper order and might include stuff that was previously deleted in the Daisy structure. While the MP3's or WAV's are normally formatted audio files, a Daisy book has additional files that your PlexTalk uses to navigate and play the book. With these Daisy files, you can add headers, edit out unwanted info, or add other new info. These files also tell your PTR1 how long the book is and some other information that help it tell you all the things you want to know.
An MP3 disk, while using the same audio format files as Most Daisy books, does not include the Daisy files. As of my version of firmware for the PTR1, you cannot back up an MP3 disk to a PC card. You can only insert the disk into the PlexTalk and play the MP3 files. I thought I'd read recently though that there was a firmware update that allows this, but I'm not sure about that.
Hope this explains what you wanted to know.
TTFN, Marilyn
