Audiobooks questions!

Had a grand old time listening to this over the weekend and whilst putting the files onto disc and listening a few questions came to mind.

First, were audiobooks ever printed onto minidiscs for sale? Possibly after the implement of Hi-MD when it could be easier to fit more on fewer discs? Not sure how popular the Audiobook was/is in JP/UK as they were the biggest markets for prerecorded discs and the format in general.

Secondly, Whilst moving the files over via the Web Minidisc Pro, I noticed that since each file had a title, a not a short one, it would invariably not let me put quite as much audio as should fit in the LP4 format and every time gave me a error about character length. Something to the tune of "The disc's title seems to be corrupted" and would then stop transferring, and when I took off the last couple which hadn't put all the characters on, it worked just fine. Not a huge inconvenience, but it would have saved me one whole disc for the full audiobook. Curious!
