Scott: For Book Port, you'll need Format 4. I do use Audible Manager to download the book, so it gets saved on my PC. Then, after it is downloaded, I go into Book Port Transfer and select the book and send it to the BP.

Can someone please enlighten me as to which format you nneed to choose for audible content on your bookport? I'm thinking of trying out audible and would be interested in hearing from folks after purchasing some audio content, do you need the audible manager to download the content or simply use the bookport software to download the audible content and send it to your bookport? Thanks to anyone who can assist on the above issue.
