Thanks for the quick and very informative reply. I am not familiar with Audible books but I will research them. I am more familiar with the library downloads of Overdrive and NetLibrary.
I do have Nero Express Essentials though. So as I understand it: I download these audiobooks in whatever file format they are and then I change them to mp3 files so I can load them on the v1 Sansa 200. Correct?
