So, apparently there is some sort of incompatibility between podbooks compiled with the Windows
MP3 to iPod Audiobook Converter program and Mac OS X 10.7 Lion. The files download with an extra ".mp4" extension after the ".m4b", and Finder identifies them as MPEG4 movies.
Unfortunately, unless the makers of the software release an update to fix this (and since the software hasn't been updated since 2008, I'm kind of guessing they won't), or Apple releases an OS X Lion update which fixes it on their end, it will cause all of your podbooks to open in Quicktime by default. Oh noes!
Luckily for you guys, between
cybel and myself, we've got workarounds for everyone!
WORKAROUND FOR OS X LION PODBOOK LISTENERSETA3: The FIRST thing to try is changing the file extension manually in Finder, by double-clicking on the filename, selecting the ".mp4" bit and deleting it, so it just says ".m4b". This should totally fix the problem. However, if your Finder hangs--which it may, it may not--continue onto the next step.
Control-click on one of the affected files and select "Get Info". Use this menu to set iTunes as the default program for these type of MP4 files. Once they are actually opened in iTunes, they should play just fine.
Please note that this WILL cause all of your MP4 movies to open in iTunes by default.
ETA: If you don't want this to happen, in the "Get Info" menu, you can choose to just open that particular file with iTunes, but do note that you will have to do that with EVERY file like that.
ETA2: Although apparently, this may cause the files to behave like MP3s--look for them in the "Music" section of iTunes. You'll have to go into the "Options" tab and manually select "Audiobook" under type and check the "Remember playback position" box to get it to function like a 'book again, like you would with any MP3.
(Thanks to
cybel for this info!)WORKAROUND FOR WINDOWS OS PODBOOK COMPILERSUse
Chapter and Verse instead.
eosrose has a lovely tutorial on how to use it
here. It's a bit fiddlier than the MP3 to Audiobook converter--there's at least one extra step involved (and about three, the way I do it), and it takes more than three times as long to load on my computer, but it gives you a lot more control over the podbook creation. I use this program for all of my podbooks that have chapters.
MOREOVER, the podbooks compiled with Chapter & Verse should work as expected in OS X 10.7 Lion.
Hope that gives everyone any info they should need! If you have any questions on this issue, feel free to ask here.
