PRS-600 Listening to an epub file on PRS600

[just_kev]

Hi,
I have just "borrowed" a book called "And another thing..." by Eoin Colfer from my county library. At the end of the book it says:

"Listen to the first chapter of And Another Thing below"

Ha Ha, needless to say there is nothing below that can be seen by human eye or heard by human ear. Not on the PRS600, or Reader Library or Adobe Digital Editions, and Calibre won't open the file because of the DRM?

The file is so big that it must have a sound track embedded in it? Can you do this in an epub format book? Has anyone any idea how to listen to it?

For those of you who are interested, the book is the sixth in the Hitchhikers Guide to the Galaxy Trilogy! So far it is OK. But it is so long since I read the others that there are some "history" that I am not following.

It seems to me that this could really be a great e-book if all of the snippets from the book were interactive and used audio and visual aids.
