@matech - if you were able to find it with a search, maybe it just wasn't imported with the same metadata as all your other books? Maybe you might want to look at "Get info" on that book and compare it to anotherbook that imported well? if you do, compare "Media Type" and other metadata fields like that to find the differences. I would (personally) think that if all of your books come from audible.com, they should import the same, but what do I know.. I am thinking that Maybe it imported as Spoken Word or podcast or something else while all your others are "AudioBook"
@Aimster121, yea... older devices are screwed. My iPhone is all that works for me now. All my iPods are oldschool. I have to resort to 're-encoding' if I want to use them... which I can't\won't\don't want to even think about.
*VERY* unfortunate and there is really no other way to describe it. I really can't understand why it has to be so difficult.
(all my reasons are "tinfoil hat" like, maybe Our Favorite Device Maker wants audiobooks et al. to take up more space so that we stop thinking 8/16/32 Gb should be standard....)
Hope this helps... respond if not, and I'll do my (meager) best to help.
