At the end he said it was recorded on July 26th, so I'm not sure why his numbers are off.
I can report that if you put this file in the Audible folder rather than the music folder. It can be controlled like I normal audiobook. Pause to bookmark, skip ahead 30 secs or back 30 secs. Of course, since it's in the Audible folder you cannot read on your Kindle and listen to the podcast at the same time (why would you want to). To listen and read, the file will have to go in the music folder.
BTW, this file is 25MB, so I'm running it from my SD card.
